The Robb-Talisa scenes from Season 2 Episode 8. I still think Talisa is a Lannister spy, the whole “my poor, poor brother” story is fishy, especially coming at the time Robb is obviously worrying about his own brothers at Winterfell, under Theon’s control (presumably he has no idea that they’bve escaped from Theon and are in hiding). And her story goes on … and on … and on! They could have used the screentime for more Stannis and Daenerys.
For god’s sake, breaking your promise for lust. Where is the honor in that, Robb?
