"As for Pete standing up for Jennie, why should he? Jennie was quite capable of arguing her point, why the hell should Pete step in and completely undermine her?"

No one is saying that Jenny was not capabale.
I am not saying that he had to leap in front of Jenny like a bodygaurd,but all he had to say was "I did drink some of the wine" and the argument would'nt have even began,but instead he chose to stay silent.
