((ok, quick history of Terenia for those of you who didn't understand or weren't following her conversation with Mike. Terenia was born a human, on Earth, but became an Andalite nothlit around age 10-11. She joined the military as an aristh & everyone thought she was an Andalite, albeit a slightly slow one. Stuff happened, they found out she was human, they decided to turn her into a science project, which resulted in her morphing being restored (yay new tech!). Then, through other events, she re-nothlitizes herself, this time for good and in Yeerk form. Then she got an Andalite host. This time she's stuck, there's absolutely no way to restore her morphing capability, so she'll live life out in Yeerk form.
I know, way too complicated. That's what happens when you have 13 years of backstory on a character.))
Terenia doesn't answer Mike's assessment. She knows that if he works it out for long enough, he'll figure out who she works for. When the newcomer bursts into the bar, guns a-blazing, she turns her attention to them, the conversation not forgotten, but put aside for the moment. her hands drift down to her holster and she stiffens slightly, but she remains facing the bar, using only her stalk eyes to watch the events as they unfold.
