Vex will be moving to aid/defend the deepsea merfolk, particularly the fishers led by Po'ele'ele, in thanks to aiding her group when the circle first arrived. She doesn't particularly care for following the queen's orders - she's not one of her subjects, after all.

She has noticed that the deepsea folk look quite alike to the newly arrived mermen, and she'll want to ask questions between both parties.

Aside from this, she's a little less interested in dealing with the rift since her powers don't help in that regard - unless throwing currency the rift communicates that it directly wants would close it. :|a She will offer said powers to aid the negotiations group, however.
