Does it mean anything if two people give each other “a look” whenever I start talking?

The guy is really really nice to me so I don’t know why this girl would give him a look whenever I start talking. It’s weird it’s a look they exchange. Like we where working out together since we all have a similar time slot and know each other via my old coach and he was trying to encourage me like my ex coach did he said come on four more and I jokingly said “ugh four more” and she walked passed, stared at me and they exchanged a look.

another time he said see you later and I said with a stutter s-see you later just our words kind of clashed and they again exchanged a look, anytime I come around they look at each other funny. Do they dislike me? The guy seems fond of me and the girl seems standoffish toward me and always watches me and his interactions but him and her have a good and closer bond too
