First of all, apologies for the quality of the screen shot there; I was uploading another story while listening to the audio of this clip, so - much like Scarlett - I had no idea what was coming. Fingers are still shaking. That and Chris was moving so fast it was hard to pin down the exact moment of "OHHOLYMOTHEROFGOD!" on her face, but you probably get the point. 

See. You think you know someone... Given Scarlett's reaction, Ellen was quick to point out "It was his idea!"
 

Once the nerves had presumably stopped jangling, Chris and Scarlett then played a game called 'Avenger? I Hardly Know Her.' Of course there are paddles involved.
