Cece mentioned to Jess earlier when she met the new roommate that there was something growling in his carrier. They never explained what it was.
I was surprised Jess wasn't thrilled to have another roommate who likes to sing to themselves like she does.
The only thing I didn't get about the ending was why they all went to their separate rooms to dance. Since they were all happy to have Nick back, why didn't they gather in the living room and dance together?
It was a good episode as usual. I'm just sad there won't be new episodes until the next season starts. I hope they'll continue showing reruns of the show at its usual time on Tuesday night. I'm guessing they will since they've been showing double episodes lately, one new and one old.
