I think it was a Grimm. One that Cinder has learnt to control (possibly by that symbol on her hand).

Also, Merc has cynbernetic legs. I am never more pleased to say a theory got shot down. My old theory of abusive drunk dad is gone; new theory is that Merc got caught in the crossfire between attackers and his dad as a kid, lost his legs, but still had a good relationship. When Cinder recruited him, they'd been under attack from more people wanting to take down the assassin, and Merc drove off the attackers but his dad died and their house caught fire in the process.

Emerald's semblance is confirmed; she makes hallucinations. Neo theorists, eat your heart out.

Speaking of Neo, she's useful. She's the 'ambulance' driver. At least they put her to use.

All this stuff happened around the time Blake left the White Fang. Adam is one of the current leaders of the White Fang. Blake seems to have been his protegee. The Leuitenant seems to be personally invested in getting her back; older brother type? As in a proper older brother type, not a mentor older brother.
