Favorite episodes are probably
Season 1
Lion 3: Straight To Video - Rose made me FEEL that maternal love
Alone Together - I think this episode was great because it reminds us that Steven is not just any crystal gem, he is the first of his kind. Steven and Connie fusing might have been foreshadowing on just how emotional and connected fusion is. Also Stevonnie was flawless.
Ocean Gem - Lapis
The Return/Jail Break - This mature and rich atmosphere for these episodes is just another example of what separates SU from other "kids" shows being aired. These episodes were action packed, emotional, revealing, and completely hyped me up for the next season.
Season 2 so far:
Joy Ride - this episode was so cute and such a nice funny break
Story For Steven/We Need To Talk - I just love every episode when Rose makes an appearance because she's just so dazzling as a character. Learning more about her is amazing everytime.
Sworn To The Sword - I love how Connie has progressed from being shy into this mature sophisticated and strong young lady. She wants to be able to fight on her own and protect Steven, her character is an outstanding role model and well executed. Not to mention Pearl's absolute devotion for Rose comes back yet again, highlighting one of Pearl's biggest issues.
Keeping It Together
Cry For Help
These two
REALLY punched in exactly how much fusion means to Garnet. And Pearl's huge mistake violating Garnets trust with fusion creates a schism within the gems for the latter episodes. I loved that the issue wasn't "forgotten" and that they really played out exactly how sacred fusion is.
