Same here! High five!
I honestly didn't know what I was doing. I guess I was thinking it'd be in the cave again, but then I realized.. legendaries are only a one-time-appearance thing. Silly me.
And then... I ran into a shiny buneary while in the Eterna Forest with Cheryl.. and you know how we can't catch Pokemon with a partner
I wanted to ditch her right there and then!
