== Synopsis ==
A rival of Violetta’s comes to attack Team Sonic, but it’s not by her will.
== Plot ==
Sonic is sleeping, when a note with an insignia falls onto his face, causing him to wake up. The next morning, he shows Team Sonic the note, outraged that he looks terrible. Tails offered to scan it, until Violetta intervenes, explaining that the logo is her twin sister, Crimson’s, mark. The others are shocked by her having a sister, but she brushes away their questions quickly, then saying she didn’t mention Crimson because she thought Crimson was an embarrassment. She recommended that they all stay on high alert, because she knew Crimson specialised in sneaking past people. Then there was a montage which showed everyone putting defence systems, all except Sonic, who had been deprived of sleep and had taken an extra long nap. 
Later that night, a figure in a red jumpsuit and hood came to kill Sonic when Violetta showed up, since she was guarding Sonic. Expressing how she detested the fact that Violetta constantly outdid her, she attacked her but Violetta immediately subdued her with the help of Knuckles, Sonic waking up and seeing the resemblance between the two female hedgehogs. 
The next morning, Sonic came to visit Violetta when he found her in an intense interrogation session with her sister, offering to leave when Violetta told him to just wait a second. Shouting, she got only a vague piece of information, deducing it to find out it meant they will go for Shadow. Sonic tried to intervene, but Crimson teased her about Violetta’ ex-boyfriend, Zac, which Sonic got jealous about. Violetta became slightly jealous since Crimson claimed she had stolen her ex from her, but she brushed the feeling off and set out to find Shadow with Sonic, contacting the rest of Team Sonic. 
Meanwhile, a black hedgehog with blue streaks had approached Shadow, telling him that he overheard Team Sonic joking about him, offering to help him take them down when he saw Shadow angered. The two made a partnership and set off. 
Sonic and Violetta were in the Badlands searching for Shadow when they got contacted by Tails that they were under attack by Shadow and another, and the two dashed off to help. When they got there, Violetta offered to build a device that could transport Zac over to the other side of the universe, which Sonic agreed to, but he made her promise to stay out of the way until then. He joined the fight, Crimson joining Shadow and Zac, having broken out of her bonds. He was no match for the three, but Violetta, having finished the device, came into the fray, stopping Zac in his tracks. Sonic persuaded Crimson to stop, and Violetta explained to Shadow that nothing was said, saying that Zac was very manipulative.She explained to Sonic that Zac could take down both of them, so she summoned her suit, and Sonic got given his own enhancing bracelet, and they started fighting Zac. They conversed in the battle, deciding that Violetta would distract Zac long enough for Sonic to come round the back and use the device. They carried out the plan, which worked, and they pulled Crimson up, stating that both her and Shadow would make a good addition to Team Sonic, which Crimson refused at first until Shadow said yes, then she immediately agreed, hinting that she has a crush on Shadow. 
Later, the two sisters were standing on the beach. Crimson immediately rejected her attempts at light conversation, until Violetta mentioned someone, which they both seemed frightened by. They agreed that they knew what might happen, and the episode ended there.
