Plot hole: When Geoff meets Hitch in the zoo, he says he got his number from Albert Brennaman, but we have not seen a connection between Albert and Vance, so there is no reason for the team to tie it back to Albert and Hitch. Even if the tickets for the club being in Alex's name for Albert and Allegra's date were a clue, then Sara would not have been surprised to see Hitch at the zoo... So how did they know to use Albert's name? Why wouldn't they just use Vance's name, since they actually got the connect from him, believing that it was in fact Hitch's job to hook men up with women? (01:21:30)
Plot hole: In the part where Allegra is speaking to Albert in his office doorway and Hitch slips the pen in his pocket, how did he know she looked away? He's behind a solid door.
Suggested correction: He (and we) can hear her rummaging through her purse.
