So, about next issue. They'll have to give that sentinel something special to prove it can be a trouble for Jean, Kurt and Laura.

Kurt could teleport it's head off. Or teleport Laura to its neck and have her hack it off with her claws.
Heck, Jean has been taking down sentinels for years, ripping them apart and floating them easily.

I hope next issue, the sentinel is easily taken out in a page or two, so we can move on to important things like, gambit, the evil friend, Cassandra Nova/Jean interaction, more explanation on the save the world plan, interaction between Kurt, Jean and Gambit.

I hope the issue won't be them struggling with the sentinel for half, until triniary is able to hack it, then a lame possession of one of the teammates by Cassandra, with gambit appearing out of nowhere
