'Scandal,' 'Happy Birthday, Mr. President': Fitz And Olivia Flashback To Steamy Oval Office Hookup (EXCLUSIVE VIDEO)

After "Scandal's" shocking cliffhanger at the end of last week's episode, "Defiance," there are a lot of pieces of a very complicated puzzle to put into place in this week's episode, "Happy Birthday, Mr. President" (Thurs., Dec. 6, 10 p.m. ET on ABC). Most importantly: Who shot Fitz?

"Happy Birthday, Mr. President" promises to answer that question -- and they do, in the last few frames of the episode -- but in true Shonda Rhimes style, the answer will only leave you with more questions. A lot more questions.

But the ride to get there is a very revealing one, especially with Olivia Pope (Kerry Washington) officially returning to work at the White House to help do damage control. There are a lot of memories for her there, mostly with Fitz (Tony Goldwyn), and we'll get to see quite a few notable ones via flashbacks to the first few days he was in office.

How did those two celebrate his presidential victory? Watch HuffPost TV's exclusive sneak peek above to see their steamy hookup scene christening the Oval Office, and to see more of Olivia's emotional reaction to Fitz's life-or-death situation in the present day.

Tell us: What do you think will happen to Fitz? And is this the sexiest scene yet on "Scandal"?

"Scandal" airs Thursdays at 10 p.m. EST on ABC.
