"I can't stand you – you – you! Ugh!" She pounds her fists on the table. "I don't see why I keep feeding you!"

Of course. Jin does everything better. Everything. Everything but argue – everything but answer when she asks a question. That's what he's for. The remarks he thinks are witty, the arguments, the lewd speeches and, sometimes, the laughing along with her.
