That must've been a nice surprise, they must know you well or maybe you just drove them mad talking about it.
If you get bored of pretending not to know you could always just mess with them and act disinterested in RDR2, fake a 180 and start talking about how RDR2's gonna be a disappointment and see how they react although that may be a bit of a dick move and it's unlikely anyone who's seen any trailers or info about RDR2 would believe you.
