Oh man…I have no idea which would be more excited. Because for Roxy, this is the first time she met her mom ever due to the whole “genetic ancestors gave us life centuries ago” thing. So this is her meeting her idolized hero.
While Rose lived with her mom, had a one-sided passive aggressive relationship with her, only for her to die. And Rose did care for her, but wanted a chance to show it again.
Basically, they both deserve moms.
