Here at Wetpaint, we like to analyze every little clue we can about upcoming episodes. In that spirit, we've taken a close look at the sneak peek photos from Grey's Anatomy Season 8, Episode 19: “Support System” to try to figure out what they reveal about the episode.

Mark vs. Richard: It looks like it will be temporary chief vs. former chief as Mark (Eric Dane), who is filling in for an MIA Owen (Kevin McKidd) and Richard (James Pickens Jr.) clash in the OR.

Ladies' Night: Awkward, or Fun? Bailey (Chanda Wilson), Callie (Sara Ramirez), and Arizona (Jessica Capshaw) join forces to give Teddy (Kim Raver) a fun lady's night out. But will a night out become a never-ending evening when Teddy shows up with what looks like DVDs? And why do Bailey and Callie look so annoyed in this picture?

Owen and Cristina angst: We didn't need pictures to tell us the going is going to be rough for Owen and Cristina (Sandra Oh), but the pictures confirm that they appear to be absolutely miserable
