Yah, know. I'm good with this map, there is a lot of potential for stories. I however would like Marco and Star to be separated for a little while. It would good for the story, and good for the two of them (that confession was very messy Star, and you prefaced it by insinuating you may never see him again, without actually telling him why. Both of you will need time to think).

Best case scenario. Star on her own gives us a bit of Mewni content (that we sort of do really need), and Marco gives us access to some side-character content along with showing off what skills he has left from his time with Heckapoo. Ponyhead and Tom of course, though one or both could be with Star for now since they're from Mewni, but I'd also like to see Kelly, Janna, and Jackie tag along. And yes, I could see all three of them coming with Marco to Mewni. Janna and Jackie have both exhibited they enjoy inter-demensional travel, Janna is Janna, and Jackie has some relationship things to deal with. Kelly ... not alot on her outside of she's apparently a badass.
