Re: OOC.
yelena would have shown up, for sure! she also probably brought a bottle of vodka, because she doesn’t know rose too well yet. this is the opportunity to hang out and get to know her better. once she does, don’t be surprised if she gets a surprise belated birthday present.
yelena will happily help with setup/cleanup as needed. she is there to drink, stuff her face, dance and mingle!
