It was a little unsettling to see Krei of all people look anything but sure of himself. (Post-movie; takes place after Fair and Good As New and might make more sense if you've read the second - but it's not necessary.)
Hiro thought she didn't know he wasn't sleeping. Truth be told, she wasn't sleeping much herself.
Post-movie, Hiro has a bit to come to terms with... including some of the people involved in the team's first mission. CONTAINS SPOILERS.
Voicemail is a great way to keep in touch when someone can't get to the phone.
A series of one-shots focusing on pairs or small groups of characters hanging out and bonding - because really, that's one thing the movie needed a touch more of. Some spoilers.

It's the first Christmas without Tadashi - and while Baymax struggles to make sense of the holiday and provide comfort where he can, something keeps bothering him.

He hadn't slept peacefully since that night. (contains spoilers)
