Oh.

Well.

This is just... infinitely worse than the bar, isn't it? The small part of her mind that isn't descending into white-knuckled panic wishes he wasn't so polite about it - someone who can invade your personal space like that just shouldn't sound like one of the tutors from boarding school. Beyond the immediate danger of someone being able to reach into your brain and do whatever they like, there's the added factor that she has been set on reverse-engineering quite a lot of the Chitauri weaponry, since they relied surprisingly highly on biological systems. She cannot allow that knowledge to terrorize another world.

Fear would keep her rooted to the spot, but thankfully, someone high enough up the chain realized that would happen in a crisis - muscle memory is more basic than higher brain function, and regular repeated drills get her heading for the door. She doesn't have much of a plan (or any plan), other than the vague one of 'find lab, lock door of lab, hide' but it's still better than the option of nothing.
