Did he grab a missile and absorb the energy?
I'm a bit 'wtf is this' about the whole issue.
I actually thought this was cool. Always thought there was no reason why Gambit shouldn't be able to diffuse/disperse/absorb energy as we have seen instances of him making objects disintegrate without an explosion. Of course, I suspect Tini probably doesn't know what the hell she is doing and this will not be picked up anywhere else.
However, if this somehow becomes a part of his power set then that would be the silver lining for me in this otherwise atrocious series.
