I recently re-watched all of season 2 and it refreshed my memory, especially the romantic development between Kara & Mon-El. Here is a great fan made 17 minute youtube video showing all of their interactions episode 2x01 through 2x13.
I guess I am officially a shipper for KaraMel ;^)

Kudos to MelB for delivering amazing performances the last 3 or 4 episodes.
