Cristina has to lie: The other big plot that we know about revolves around — surprise, surprise — Henry's death and Owen's (Kevin McKidd) lie to Teddy Altman (Kim Raver). Teddy ends up asking for Cristina's help in the OR, still oblivious to what happened, and Cristina is forced to keep the lie alive while operating. Because poor Cristina hadn't suffered enough emotional trauma for one day.
Love triangle fun: It wouldn't be Grey's without a little romantic trouble thrown in with all the high drama. This time it's about Mark (Eric Dane) and Lexie (Chyler Leigh). Things are sure to get awkward when "Lexie finds herself working alongsideMark's new girlfriend, Julia."
Remember to tune in to the episode on Thursday, January 5, at 9 pm ET/PT on ABC.
