For you, there aren’t any side effects of which I’m aware. The dosage you take allows you to decide when your mutation is exhibited (to an extent – I believe it can sometimes still be triggered by intense emotion).

For me, losing my mutation entirely is the side effect. When I’m taking the serum I can walk and feel my legs, but I no longer have telepathy.

I’ve seen Raven, or spoken to her. I believe you’re correct about this place being out of sync with our timeline. Has your research discovered anything concrete?

My injury was caused by a deflected bullet. I’m sure you have an idea of who might be able to do such a thing as causing a metal projectile to change its course.
