I sometimes rewatch the older episodes to find what I missed that contributed to the later stories that a poster may have pointed out.
That’s the part of the show that is the most fun for me after learning new stuff with each new episode then re-watching past ones with that new information. After watching “Manhattan” I had to re-watch Tallahassee just because we know that Neal is Bae now. Or like when Belle loses her memory I had to re-watch “A Land Without Magic” just to see how Rumple was able to get Belle to trust him when she didn’t have her memories then either. Then of course that made me want to watch all the Beauty and The Beast episodes from Skin Deep on lol.
