I'm a grown up and yet I felt really disappointed and sad that they took of nabu like that. I'm a person who doesn't like seeing good guys being written off in a show. I was really hoping they bring him back.
Also, I felt that the battle was way to short also. They finished them off in 5 min, I watch and was like "What are they going to do for the rest of the episode?"
Although I did like how morgona explained how she met roxy's father and was evntually captured and the whole wiping thier memory of her clean until they reunited now. That was nice.
All in all, I think the ending could have been a little bit better but it was still nice to watch.
