Mandrake rewrite

Mandrake is introduced early in the series alongside Olive. At this point we just see him in the background as a lavender color cat watching over her. During the series we sometimes see in the background someone with lavender hair just as an easter egg to say that he was always watching since the beginning. Could even have the kid that “accidently” shot an arrow at the principal have lavender hair indicating that even though at first it can be taken as just have been an accident it was actually a disguised Mandrake trying to assassinate the principal

During the festival episode, we have a disguised Mandrake following Rosemary and the others, but he’s stopped when he bumps into someone, they have a little fight but he uses his charisma to bails himself out of the situation but he also leads the person to follow him into an isolated place for some “fun”

The episode goes the same until the end where there is a scene of Olive entering a hideout with a figure with lavender hair with the moonlight coming through the window hiding ‘em in darkness, he’s sitting on a bed by the corpse of that person we saw previously, with a dagger still embed in them. We have a small back and forth of Olive and the figure with her being disgusted and alarmed that he killed someone and that he might’ve compromised the mission while he simply states

“I couldn’t resist”

It goes for a bit more until she calms down a little and say that Rosemary is the daughter of Lavender. He’s taken a back a little and then say something along the lines of

“This throws a wrench into our plans”

The rest of the episodes follows the same (If I were to re-write the entire show I would be here for a long time) until the “Attack at Guardian High Episode”

Smoke face appears to talk with Olive and it’s revealed (gasp) that the lavender cat was Mandrake all along and he’s given the all clear for him to kill the girls.

While sneakily following along Rosemary almost spots him, she follows him into a room and Mandrake disguises as Lavender. We have the conversation go more or less the same but in this version when Rosemary says “I missed you” he visibly hesitates and gives up on killing her even though he had a lot of chance of ending her right then and there.

When they battle Mandrake later he’s no pushover, he’s mostly goes for the kill with his attacks against the girls except for Rosemary, he has a chance to kill her again but he doesn’t take it.

After the broom fight instead of going after Olive he goes after Rosemary, he binds her in magical chains and is getting ready to take her away when he gets defeated by Sage.

In the after-credit scene we have Mandrake inside a cell held by chains to the wall, Lavender comes into the room and grabs him by the throat pushing him against the wall

“Such failure…”

She kicks him full force in general region of his wound from when Olive stabbed him and pull his face up by his hair. This is one of the few scenes where we see him actually scared while Lavender stares him down.

“Mandrake… your failure here could’ve jeopardized the entirety of the mission, however you’re still useful to us, but… next time you fail at such important mission like this one…”

She grinds her first against his still healing wound to accentuate her point and cause him pain.

“I won’t be so merciful”

She lets go of him and walks out. And the season ends right about there.

If there was a second season it would be revealed that Mandrake is the result of an affair that Lavender had a long time ago. Lavender felt guilty of what she'd done but she still raised Mandrake, however instead of being kind like she was to Rosemary she was harsh (and maybe if you want to go there maybe even abuse at times). He was raised in Witch Country since a child to be an assassin and Lavender’s right-hand man and that is one of the reasons why he has a lust for killing. But he draws the line at killing family, that’s the reason why he didn’t kill Rosemary when he had the chance. Maybe if Rosemary got kidnapped and taken to Witch Country in a future episode have him be uncharacteristicaly kind to her instead of his usual psychopathic attitude. Could even have a throwaway line of him being proud of his hair (leading back to why every time he didn’t transform into anyone specific he always choose to have lavender hair)
