Chekhov's bear will be important by the end
I've brought up Chekhov's bear a few times but there are some that are convinced the bear is merely symbolic.
didn't we already see here that it was Riko and Colin/Momo who made that bear sign and put it there to keep other ppl from coming into their secret hangout spot?
Yeah there's that too...but enough attention has been drawn to the sign to make me think it'll serve a purpose beyond that.
Also we keep seeing the characters trying to avoid involving adults in their efforts to help Colin. Makes me think Bear-kun may show up to give a helping hand paw in a critical moment after they get themselves stuck in a situation where it looks like they're screwed.
