So, yeah, Andrew is Lash.

Werner von Strucker and the Hydra goons surround him, he makes some comment like "You're making me angry, you won't like me when I'm angry," turns into Lash, rips them to pieces, and Werner blows the place up in a desperate attempt to kill him. Werner looked terrified in that last shot of him. And it's worth noting he's the only Hydra guy we see escape from the building.

Lash's motivation for killing Inhumans is just a more extreme version of the concerns Dr. Garner's voiced to SHIELD. Maybe he can't control himself. Regardless, this show is fond of "x character is secretly the bad guy" twists. Ward, Garrett, Jiaying, sort of Bobbi and Mack, and now potentially Andrew.

Either that, or Trip is still alive or something.
