Interesting, I'm sure Bowtie said that Liam would be facing the elite 4 after winning the coin toss. Meh, the outcome of the battle does not affect me, since Mike and Sashia have already completed the Aloha region. They will run with their teams that did that.
Are we going by the rule that theirs already a Pokemon league built and ready or is it still building and gets finished when the group are there? After all, Mike and Sashia would already be island challenge Champions but there's no definitive champion until the league is built.
