Scarlett Siblings

We are on a mission to go find Scarlett's, or Utopia's, siblings. It's a race against time (and each other), to see who gets there first. Meanwhile, I get worried about Mizeal, a rare event, as he refuses to leave Nemo's side. Now, I really wish I could remember who Scarlett's other sibling was....
But will Nemo, Alit and Trey be ok? Will Mizeal ever leave Nemo's side? Even I, Dumon, will have to wait and see....
