to me the lulaby was a lilttle retarded because the character is a no body and its just a filler i feel you cant feel the sentiment of the characters feelings since he is only gonna be in 3-5 episodes at most unless the fillers end lol for a lulaby showing a characters feeling and the mothers & fathers death being shown like that it would fit better with a main character so the viewer can get an attachment to the character well thats atleast my feeling on it it felt like "Dude who cares" when i saw what he was feeling and the song he sang lol
