What do Du think Did Rose and Jack remember that they see each other here?

Rose maybe not, but I'm sure Jack did. Him and his Friends had a small conversation when they noticed him looking at her.
Rose however was probably just upset from ealier (this is her after she walked out of the dining room). They might have met eyes but at that time he was just a stranger. The real meeting was at the jump scene. I hope that helps a bit. :)

I would guees that since they don't actually introduce themselves oder talk at all in this scene, they probably don't count that as "meeting," but I think they do remember seeing each other here.

I'm not sure if Rose remembers. I believe Jack remembers.Even though he never mentions it, I think he remembers seeing Rose for the first time.
