Continuity mistake: Right before everybody jumps out the window of the hotel room hallway after meeting with the Scorpion, Tim kicks a briefcase down the hotel hallway. When the briefcase stops, the latches are facing the camera. Next time we see the case the Scorpion is coming down the same hallway towards it, however the case is turned around and latches are facing him, not the camera.
Continuity mistake: The level of snake wine changes in the glass as the camera cuts back and forth during the conversation in the Chinese restaurant between Jeff and Tim.
Answer: It was definitely meant to be a sexy scene, but it isn't pointless. The two were genuinely bonding during that scene and the gradual friendship built between the couples forms a major part of the plot. The sexiness between them also sets up the scene later in the film where the two kiss and Karen discretely passes a knife to Natalie. As an aside, Karen isn't played by Amy Adams, she is played by Isla Fisher. Amy Adams and Isla Fisher share a striking resemblance and are constantly mistaken for one another.
