With all due respect- ( And there's likely a little less there ) -SHIELD was started because of human threats. Non-powered individuals that would threaten our safety - freedom.

( And she'd appreciate the lack of assumptions on his part. It might be nice for him to be in a world where something like SHIELD is obsolete - where everything is nice enough and able to be understood, but people don't understand. That was why until New York things were a secret - to keep it from becoming out of hand )

Aliens trying to destroy Earth changes the game plan.

( There'd been less incidents before then - before the Chitauri had left things behind that people had swept up. That people had experimented with. It was humans that started most of the problems - people became powered or had the wrong technology from it

But there's a breath- a pause to reign in some of that irritation that had sprung from Charles' judgement. There were some powered individuals that she worked with - others that were allies. It wasn't being powered that was the problem but what you did with the power - or regular human thought )

SHIELD is gone - just before I got here.

( Technically just after - she'd been in the process of planning out how when she'd arrived, but a few jumps later she'd received that outcome )
