Rein was well-behaved during the New Year: she celebrated it with her immediate family, consume zero alcohol & didn't sneak out to go party somewhere else. Now that January 1st passed, she'll need to sneak away from her family to back home. Gabriel was waiting for her there & she needs to educate "it" about New Years. It'll be a personal afternoon between the 2 of them, alone at home and she bought drinks just in case.
