I watched it several times and I'm pretty sure she is just showing expression by opening her eyes wider and then closing them tighter etc. I didn't catch anything evil about her.
edit: Actually, now that I watch it yet again in very slow motion, I think I detect fear or urgency in her eyes just before she fades away to reveal the cheif. I think she's in the midst of some kind of struggle...maybe a moral one (join forces with Gravemind or not) or a 'physical' one (Gravemind could be trying to take over Cortana).
