Chief & Rookie because they were vaguely entertaining, although Soon & Mijung are far more important.

Wow, I just reread the "set the tents on fire" part, so Haley & Belkar is pretty fresh and funny to me, but there was sure a lot with Tarquin & Nale. It seemed like we never got the whole story with Tarq and Nale, y'know? I always wanted to know why Nale hated Malack to such a degree. Just seemed like there was an aspect of their relationship that was implied that we were supposed to pick up on. Something under the water. So it's interesting to me for that.

However, I despise Nale, and Haley's "the cart is full" gets referenced by me way too much, so Haley & Belkar. (I literally just played a Neverwinter Nights module and tried to quote it from memory while infuriated at a henchmen I wasn't allowed to get rid of, because it summed up exactly how I felt about them, dammit!)
