1) This was part of a series about Darcy and the team all living in the tower, and Darcy had made Jane and Bruce and Thor "Team Science" jackets, and Tony was pretending not to be jealous, and she and Bruce pulled out a box with one for him?
2) Darcy is going to be Midgard's ambassador to Asgard, so a group of people (Pepper and Thor and Coulson?) work with her and a stylist to buy her a wardrobe fitting the position. This one was also part of a series, but I think not all parts were about Darcy?
3) Thor comes back from Asgard and he has picked up the idea of souvenirs, so he brings things back for Jane, Selvig and Darcy. I think Jane got the floating ball from The Dark World? And his gift for Darcy was Loki's old Asgardian version of an MP3 player, which had all of his music plus video recordings of Loki studying/blogging?
Thanks for any help!
