I already love the back and forth going on between Rose and Pixie. Maybe Crow is somewhat well known with the Flowers? Maybe Cornelia has helped out with a bug infestation in the past? She'll also be more than happy to help out in that department in the future as well! She's especially fond of spiders. 8D
And Mr. Evans I think should be relatively safe from her Oyster eating habits since he's been here awhile, but random encounters are always fun!
