(he/him Alex!)
Basically, just like Alex and Samirah, you were also a child of Loki, wich meant that you three were half-siblings. You were the youngest of Floor 19, being only 14-15 when you died.
Anyways, due to that, it was easier to Loki to influence you, wich results in you being a mischiveous little bastard. In hotel, Samirah and Alex didn't worried much about that, after all, anything you did would go back to normal, anyone you killed would revive, they would contain you enough for you to not be a nuisance to the others.
But now that you, Samirah and Alex went in a quest to stop Loki from getting free with your floormates (Magnus, Mallory, T.J, Halfborn) and the other two (Blitz and Hearth), in a giant ship that was a gift from Magnus father, Frey, and that the crew so affectionately named "Big Banana" due to it's incredible vibrant yellow color, it was a whole another thing. Now Alex and Samirah were more focused on putting limits on you, so you wouldn't burn the ship down and get any of them or even yourself killed.
