It's Anya's preferred method for helping people who get stuck in VR. It's a quick exit. (Already done it earlier.) But I'm not sure what it will mean to Miri. I don't think she will get shot now anyway.

I actually need Anya to die in here at some point. It's important for her storyline.

Excessive pain, stress, confusion or in the case of imminent  death the system instantly boots you out and issues a cool down period. After that you can return.
