So we know that Rogue gifted Scott a sweater during that winter episode. But the question is how she knew Scott's size? Not too small, not too big, just comfortably fit him enough.
Maybe there's one day she went shopping with Kitty, then she saw both Scott and Kurt there too trying out some clothing there but end up not buying for whatever reason and then went to other aisles. Rogue excused herself to check the clothes Scott tried and checked the sizing tag for the sweater size estimation.
Anyone has better ideas? I am just so confused about this lol.
