With Friends Like These

It had been a couple of days since the incident with the Phoenix, and the damage done to the Danger Room still hadn't been repaired, forcing Superman and the New Mutants to conduct their training session outside, on the rear cliff overlooking the sea.
It was currently early Friday morning, and Superman, in uniform, was instructing the New Mutants, also in uniform, in rescue procedures, with Nightcrawler's assistance. The objective was for each of them to repel down the cliff, safely strap the victim – namely, Nightcrawler – into a stretcher, and lift him to safety.
So far, it was going well. 
Superman hovered a few feet from the cliff, watching as Magma repelled down the cliff with the stretcher, stopping where the "unconscious" Nightcrawler lay. She quickly and carefully moved Nightcrawler to the stretcher, and strapped him in, before tugging on the line, signaling the others to start pulling them up. The rest of the team responded, and Magma and the stretcher began to rise, bumping into the cliff-side lightly, before she could grab the ledge and pull the stretcher up.
The exercise complete, Superman touched down next to Magma.
"A good try, lass." Banshee commented.
"Minus bumping into the cliff wall." Bishop added. "That cost you 5 points."
"Uh, Superman?" Multiple asked. "Couldn't you have saved Nightcrawler?"
Banshee and Bishop looked at each other and then at Superman.
"Aye, he could've." Banshee nodded.
"But it would help if you knew how to in the event he's not present." Thunderbird informed Multiple.
"Tovarisch, get into position." Colossus stated to Nightcrawler.
"Jawohl!" Nightcrawler agreed, as he unstrapped himself, before 'porting away with a bamf!
"Okay, Boom-Boom, it's your turn." Superman said...but he got no response. "Boom-Boom?" he repeated, looking around...and sighed, as he walked over to Tabitha, who was sitting on a rock, listening to her CD player. Superman simply lifted the headphones away from her ears.
"Huh? What the..?" Boom-Boom exclaimed, and then smiled as she saw who it was. "Oh, hey, Super-Cutie. What's up?"
"Tabitha, this is the third time this week that I've had to do this." Superman said sternly. "I'm afraid that there will have to be consequences, this time."
"Sorry, sorry!" Boom-Boom laughed, saluting. "I'm going! Don't get your cape in a twist!" With that, she started to get ready.
Superman floated back into the air, hovering down to talk to Nightcrawler. "Hang in there, Kurt; only one left." he said.
"Who?" Nightcrawler asked, his eyes staying closed.
"Tabitha."
Nightcrawler's eyes opened in horror. "Boom-Boom?!" he cried. "She's crazy! I'm a dead man!"
Superman lightly chuckled. "Hey, she's not that bad..."
"Look out, everybody!" Tabitha called from the top of the cliff, as she started her descent. "Boom-Boom is bombin' in! Whooohooo!"
"Mutter of Gott, I'm going to die!" Nightcrawler moaned.
Superman groaned. "Of course, I could be wrong."
Boom-Boom grinned as she came to a stop before Nightcrawler. "Hiya, cutie."
Nightcrawler grimaced. "Hi." he replied. "Listen, I have to know: are you insane?"
Tabitha grinned. "Last time I checked!" she replied, as she started loading Kurt into the stretcher. "Anyway, what's up with the codename? 'Nightcrawler?' Why not something cool, like 'Wild Blue Yonder Boy'?" Then, she called out, "Okay, we're good to go!" At that, the rest of the team started to pull them up...
...and Nightcrawler promptly rolled out of the stretcher, plummeting towards the sea...before he 'ported back onto the cliff.
Superman frowned. "The victim wasn't secure, Tabitha; you didn't strap him in." he said. "You just lost 15 points. You'd better be careful on the ascent."
"Fine, fine!" Boom-Boom said cheerfully, as she looked up. "Well, those rocks look tough to navigate...so I'll just boom 'em out of the way!" She quickly formed one of her explosives...
"Tabitha, no!" Superman shouted, but it was too late; Boom-Boom threw her charge, and it exploded in an impressive blast of moderate size...causing numerous rocks to break off the cliff, raining down on them, causing Nightcrawler to fall off the cliff, knocking him out, as he plummeted towards the water.
Instantly, Superman darted down, catching his teammate and carrying him over his shoulder, before flying up and grasping the stretcher-cable, towing it and Boom-Boom up, landing on solid ground. As Superman set Tabitha down, Nightcrawler started waking up. "You okay, Little Blue?" Superman asked.
"Ugh...I zhink so." Nightcrawler replied. "Zhanks, Big Blue."
Bishop fixed a gaze on Tabitha.
"This session is done." He spoke.
"Everyone report to the infirmary; Kurt needs to be checked out." With that, they all headed to the infirmary, Superman carrying his still-dazed friend over his shoulder.
At the infirmary, Ororo was waiting for them; once Superman had set Kurt down on a medical bed, Ororo looked him over. "Well, Kurt, it doesn't look like you have a concussion." She reported, with a relieved smile. "Except for a few bumps and bruises, you seem to be fine, but just let us know if you start feeling drowsy, okay?"
"Okay." Nightcrawler agreed.
"Y'all are dismissed." Gambit said.
"We need to discuss that session." Thunderbird headed down the hall, not far from the infirmary.
Tabitha caught up, looking nervous. 
"Okay, okay." She said softly, "I admit it; I goofed."
"That was more than a goof." Sunfire replied in his Japanese accent.
"You almost killed one of the X-Men." Iceman's eyes narrowed.
Tabitha flinched. 
"I didn't mean for that to happen." She said. "I was just having a little fun..."
"Training is not the time for fun!" Superman said. "You can have fun on your own time, but on the team's time, you will conduct yourself appropriately!"
Tabitha frowned. 
"Okay, big guy, no offense, but your shorts are on way too tight." she said. Smiling flirtatiously, she added, "Which, in your case, isn't necessarily a bad thing..."
"Enough, lass." Banshee cut in. "This is becoming a bad habit."
"As of now, you are confined to Institute grounds; except for school hours, you are to stay on campus until further notice."
"God, what's the big deal?! Kurt's okay, isn't he?!" Tabitha shouted. "You're bugging just because I goofed with my powers?! They're just cherry-bombs!"
"You don't get it at all. Mutant powers evolve overtime, including yours. Your "cherry bombs" will eventually turn into TNT." At that, Tabitha froze, as she looked at her hands, considering his words. Superman pointed to his head, adding, "That, Tabitha, is why you have to use this before you ever use your powers!"
He frowned. 
"Tabitha, the whole point of the Institute is to gain control, to use our powers for good." He said. 
"To do that, we all have to use them responsibly...something that you haven't been doing. I suggest you use this little grounding to think about that, because if you're not willing to learn...why are you even here?" His eyes narrowed. "Dismissed." At that, Tabitha lowered her head, and walked away.
