In other words it's kinda like a mood ring, but... your hair?

[ Somehow her answer to the question only makes the whole thing much more mysterious. If she had just said that everybody's hair changed color sometimes where she was from, Cisco would have been able to accept that easily enough. People come from all sorts of worlds, here. But the fact that she'd actually gotten her hair surgically altered to do this? Way weirder. ]

So this happened here? Recently? Is that, like, a normal thing, people getting coupons for surgical procedures they've never even heard of before? Was there a reason why?

[ It's possible Cisco is focusing on the wrong details and also overanalyzing a bit, here... ]
