I also loved how in that brief scene they established Poe and Finn being friends far better than us being told Anakin and Obi-Wan were friends in the Prequels.
Great point mate. One of the bugbears of the 3 previous films is that important friendship between Obi-Wan and Anakin was not satisfactorily seen or felt - yet it happens quite casually and seemingly naturally in TFA with Pe & Finn.
