In the Preview for next ep (ep 6), First seems to have developed feelings for "Zee" (who is Sprite). I am a bit…
He obviously think the one he’s in love with he’s the real Zee cause he doesn’t even know exists a twin, but he started to develop feelings when Sprite has taken Zee’s place so, even if he doesn’t know yet, he is definitely in love with Sprite. This is just my opinion! (:
