When Vaughn sends Sydney a text message after he goes rogue, we see he is listed in Sydney's phone as "Vaughnzee".
Vaughn: Consider this the second time you've been rejected by the CIA.
Sydney: (to Nadia) Do you want to know the truth about our mother?... Our mother put a hit on my life... Our mother tried to have me killed.
Roberts: Like I said, I'm a bad guy… but guess what? Your dad is too… I mean he's not being held prisoner… yet for 25 years he allowed his wife and his kid to think he's dead… that's a bad guy.
Nadia: I need to speak with you.
Sloane: Of course what is it?
Nadia: I wanted to tell you before you were notified through official channels… I've been seeing Katya Derevko.
Sloane: You're right… and I assume it's not on official business.
Nadia: No it was personal, I thought Katya might be able to fill in the blanks about my mother… tell me who she was.
Sloane: I see… well… thank you for telling me. Nadia… what did she tell you?
Nadia: Nothing I didn't already know… that she was a criminal, a murderer.
Roberts: (about Vaughn's father) Where do you think he was during the funeral? I mean when you were mourning by his grave with your mum. You know it's usually a girlfriend, at least that's why my old man took off.
Sabrina: Can't we just unplug it, or something?
Vaughn: Yeah, sure, if you don't mind blowing it up and killing us both in the process...

Marshall identifies Jack as "Patient 17". In Buffy the Vampire Slayer, Spike (James Marsters) was called "Hostile 17" by the Initiative in Season 4. Drew Goddard was a big fan of the show, and ended up as a producer in its last season. He is now a producer of Alias. Probably he put it there as a reference.
