I used to play Ruki in a rp group long ago. Though you could say mine was a polar opposite to yours haha. Such a great muse and so much you can do with him :D
Yes they will, and Frog is still getting his legs so to speak on his new position and name IO so yeah, it will be fun all around.
New muse is going to be the General Shop Owner in town, so Jack will likely know him well enough. He won't be new to Neverland so new and old ties are available there.
Haakon is annoyed by just about everything haha! Pike, come on seriously I think everyone picks on him at least a billion times because he's like a total spaz.
