CONTEXT: It seems as though you answered your own questions, and that's the answer I was going to give: Caleb knew (or suspected) that Nathan had heard his conversations with Ava. If Caleb hadn't tried to get Nathan drunk that morning, Nathan would have known that Caleb ALREADY completed his plan, and he would have undone the computer code that Caleb altered. <sep> Q: Was Nathan listening in on his conversations with Ava?
Yes

CONTEXT: That's a regular Microsoft Natural Keyboard Elite. It's a split key format, for ergonomic purposes (read: prevents carpal tunnel or repetitive stress injuries of the wrist). It's considered one of the best split key keyboards, with nice heavy clicky action (for a membrane based keyboard). It (the whole series really) is consistently ranked as one of the best keyboards. It's an off the shelf product, not a specially designed prop. Source: looking at the one ten feet to my left. <sep> Q: What type of keyboard is Caden Cotard using? A: That's a regular Microsoft Natural Keyboard Elite. It's a split key format, for ergonomic purposes <sep> FOLLOWUP_Q: what job does his character do in the movie?
No

CONTEXT: Bran is believed to be dead. When Robb marches to war, Theon Greyjoy betrays the Starks and takes Winterfell. Bran and Rickon escape.

Whoever marries her will become Lord of that region. <sep> Q: Why is Sansa Stark so important?
Yes
