Marc : He would be more concerned about you than your powers. It'll give him more reasons to not let you out of his sight.Steven : Steven would worry. He'd be worried about you and how the lack of powers may affect you if you got attacked by yourself.
Layla : Layla would attempt to try and do some research on how you would have lost them or how it was possible.
Jake : You are an idiot if you think for one moment that he is going to let you step out of that door without him if you didn't have your powers.
