The only thing I can think of that might make a difference is from the last episode of S2 and is forgotten after the first episode of S3.
Season 3 is mostly stand alone, minus a few things (who Raffi is, for example).
@b4cks4w I only watched season 1 and 3. There's enough exposition in season 3 that I didn't need season 2.
@b4cks4w Yeah, you can. You don’t need to watch seasons 1 or 2 to watch 3. You can start at 3.
