I know Betty is very smart, but it didn't take a lot of her brain power to come up with the right answer to Milagros' issue. Seriously, there's always the simpler way, and even better when you're good friends with the one you're curious about. Let's hope Milagros will at least try to make it up to Wilfreda… though unfortunately it's easier just to ask Betty I suppose.
Maybe brushing Trixie's hair will give Milagros confidence and luck to at least get back on good terms with the little witch.
Also, that's not a Trixie doll. :-P No antennae.
