Now this is an interesting clip from tomorrow night's Marvel's Agents of SHIELD fall finale. We open with Billy Koenig (Patton Oswalt) and Raina (Ruth Negga) in a room together when Skye (Chloe Bennet) knocks on the door to get them. Just as they leave, Melinda May (Ming-Na Wen) attacks and the two ladies fight. Hopefully we'll find out why tomorrow night. It looks like Skye has definitely been training.
