Ran still thinks that the ways to defeat the Santa-bot are supremely silly, but that's really exactly what she needs.
And being a florist, it's easy for her to get plant bits.
Fortunately, it's late enough in the day that the shop is fairly quiet when Ran scampers in. "Omi! Do we still have too much holly and mistletoe?"
"Um, yes?" Omi blinks a few times at the unusually hyper Ran. "What do you need it for?"
Ran stops her cheerful rummage through the fridge and looks up at Omi in cheerful confusion. "I'm not completely clear on that part. It's supposed to stop a robot."
"..." That doesn't cover it enough for Omi, so he does it again. "... Nexus?"
"Yeah. If it was here, I'd want my sword."
"Right, of course, take what you need and tell me if I need to order more." Omi walks away shaking his head, but relieved that Ran is acting more like her old self again.
Ran picks out some of the best bits and PINpoints back to the Nexus.
