Nick Fury congratulates you on Atlantis and wants you to go on your mission to talk to Mandarin. Also if you talk to him again, he'll ask you to get Ultimo Schematics at the Mandarin's Palace.
There's not much more to do except go the labs and talk to Weasel. Right or wrong password, he'll now ask you to find out who to trust for help:
- Talk to Dr Pym about Cebulski.
- Talk to Vision about Beroge.
Cebulski is the person whom Weasel should talk to. Whenever you're ready, talk to Wingfoot and he'll take you to Valley of Spirits.
