Marco and Star
Okay he really shouldn't tell Star things like that because it really would be kind of interesting to see what would happen if she had the keys.
But then he diverted her nicely by thanking her and Star hugged Marco. "I know it's not the same without him here but I still wanted you to have a birthday party. And just think of how happy my mom would be that I was party planning. She might think I was accidentally absorbing all the things she's told me over the years."
