So I was trying to do the Halloween event, and I forgot to show Lingot my Chespin before evolving it into Chesnaught. Is there a way I can get through this part of the event without catching another fresh Chespin? I ev-trained it, so I don't want to re-train another one, thanks Edit: Attached pic

I accidentally ran away from Keldeo and it despawned. Can I get another encounter with Keldeo please? Thanks! Edit: nevermind, I didn't notice that it will respawn after walking away, sorry for the inconvenience.
