I expect Cole to find Johnny, fill him in on things, then the first major action scene happens and Cole is the first fatality. Cage should've been the main protagonist in the first movie, it should've had Lewis Tan just play the part back then.

I believe it means they're immune to unwarranted telepathic probes and such. But if they are actively aware that someone is communicating with them (which I'd imagine they'd feel it when the "call" comes in) they can allow them in.

Her powers don't work that way. Even if she had no limit to the amount of powers she could absorb and keep, it doesn't necessarily make her Omega. It has to do with the upper limits of those powers and what she can do with them. Now if they retcon her powers to be some sort energy abortion that manifests as power absorption then maybe.

It only makes sense that her force fields can block sound since they basically manipulate light to make things invisible, but the fact that she has control over whether the fields are sound proof or not is crazy.
