Most definitely! Yusuke can always use more people to cause mischief with. I'm not sure how long it'll take him to leave Azalea once he gets there, much less make his way up to Mahogany, but they can always continue talking over the network until they're finally in the same location again. AND WHEN THEY ARE, SHIT WILL PROBABLY GET WRECKED, BECAUSE YUSUKE IS AN EXPERT WHEN IT COMES TO BREAKING STUFF. It is one of his special talents.
