He seemed like good ol’ Han to me. Trying to talk his way out of certain death, making wise cracks and when one of them sees BB-8 and assumes Rey and Finn are on board he tries to save them by acting as if they didn’t exist. Sounds like Han to me.
I’m not saying one shouldn’t change his behavior in his life, but I myself think in that scene he acts more like some kind of comedian than the cold-blooded cowboy of the OT, the one who shoots first, asks questions later. He should’ve just said “Boring conversation anyway” and blasted his way to the Falcon 😄 , instead it reminds me of his deleted line in ROTJ, that is Han trying to do an Indiana Jones’ impression or something :\
