GIFT EXCHANGE: Josak, Miranda, and Alma would definitely sign up! Rayflo...maybe if he thought he had a good chance of getting a loli. Itachi and Ava are a definite no. XD Unless someone manages to forceblackmail convince Itachi.
Alma loves the sound of a snowball fight and would want to help with the tree!
And of course, Josak will sew late into the night if needed to have all the gowns and suits ready!
And I volunteer Miranda to find Hei? She'd try to use Time Record to at least keep him warm until she got him to the hospital, but there are plenty of reasons why she wouldn't use it and just call for help instead.
