When someone bursts out of the portal who isn't supposed to be there, Miko's first response is to shift her stance, completely ready for a fight, but when she actually sees who it is her reaction becomes slightly less "oh look an enemy" and more "oh my God it's this guy when is he going to get over this crap".

The fact that she looks about ready to try and shoot him does not change.

"Oh for-- God-fucking-dammit, dude, what are you trying to pull now?!"
