Shame it seems she won't be a squadmate this time around. She's instead going to be working at Grissom Academy...as a teacher. I'm more than willing to be the students will think she's the coolest teacher ever.
I personally, depending on how you played ME2, like to imagine her really switching it around. 3/4 sleeved shirts, a complete head of hair, about neck length. But that's just me, and really only in my playthrough where I romanced her. In other versions I'm really digging the idea of this haircut, though whatever happens I will have a moment of missing the shaved head business. So Jack.
