[Saint Walker had seen Mabel at her booth before, busy with someone or another, but had not approached her. He approaches her later on in the day when there's a lull in passer-bys eager to pat Waddles with a smoothie in hand, one that he sets in front of her.]

Good afternoon, Mabel! I felt that you could use some refreshment.

[It's not just a smoothie, though -- it's one of those smoothies with plenty of vegetables inside. It tastes like fruit, certainly, but should she look inside, its true nature is exposed by its green colour.]

You seem to have been busy throughout this event!
