Ham-fisted recruitment
There had been a big incident with monsters and the armor. Followed by her having men in suits from the government bringing her in to have a very long conversation with her. She had been very tired from the fight and had to fight to not let anything slip.

But they knew about the armor. They knew about the fact she fought monsters and was pretty good at tracking information down on them. They knew pretty much everything about her.

It was very unnerving. And even more unnerving to be left alone in that windowless office to just wait.

Apparently someone wanted to talk to her.

She was having an 'oh crap' moment.
