Glee is back tonight, and Season 4, Episode 16: “Feud” sounds like it's going to be full of plenty of dramatic battles. Between Will (Matthew Morrison) and Finn (Cory Monteith) fighting over Finn kissing Emma (Jayma Mays) to Sue (Jane Lynch) blackmailing Blaine (Darren Criss) in order to try and get him back on the Cheerios, tons of people are about to go head to head. Let's not forget about Santana's (Naya Rivera) vendetta against Brody (Dean Geyer). She's determined to prove that he's up to no good.

FOX has released a number of sneak peeks and spoiler clips, and even a full song performance. Here's a look at all of the spoiler clips that are out there.
