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.
yet it happens quite casually and seemingly naturally in TFA with Pe & Finn.
And then again with Finn and Rey. While I believe that they’re not meant for each other romantically their friendship was developed pretty well. I mean even though they barely knew each other I could feel genuine woe emanating from Rey as Finn was being dragged off by a Rathtar.
