NegativeSoul said: Also I suppose she still has some, problems she needs to work out (Dat Repel Technology).
I think it's more an appreciation gained from spending pretty much the vast majority of the game using them than that she's still using them.
When you spend most of the game getting by on them alone, I can only imagine how much of a dent they'll make in your wallet, nevermind how it must smell (it IS everything-repellent that you presumably spray all over you) . . . there's a lot of ways to improve the things, for sure (least of all their duration, try getting from Point A to Point B anywhere in Alola using Repels and you'll marvel at how many you use).
As an aside, dat Alolan Exeggutor pen . . . think she still remembers the one she encounters with you?
