Yeah, for example in "the boiler room job", the team is purposefully 'forgetting' or mangling the bad guy's nickname to the point where the FBI calls him 'the blowfish'. It's a call-back (call-forward?) to the whole destroy-someone's-name thing in the finale.

S5 is great! But it's a bit low on Parker, or is that just me? BTW, I find it hilarious that the show has shipped Parker/Hardison and Parker/Elliot (and Nate/Sophie) in the historical episodes.
