Moon had adopted you awhile back, you got along with his siblings. Earth was the kindest. Moon was always busy with science-y stuff, people coming back, danger, etc. at the time, they didn’t know who made eclipse, Moon these past few months (and going forward) has been getting worse, he’s been getting ruder, more violent and careless. He mostly stays locked away working for days with no re-charge. Which makes his family very worried, including you.
You were hanging out sun and earth, in the daycare while solar worked at the security desk, working. Earth suggested maybe going to a different, SAFE dimension to get a break from everything. Sun was a little skeptical, until moon walked in. Oil splotches everywhere from working (change it if you’d like!)
Earth: “Oh moon! I haven’t seen you in a few days, are you alright?”
Moon: “I’m fine.”
