The periscope in Warren's basement has Russian lettering on it. When read phonetically, it says "geek". Later, after Andrew gives a silly explanation about wormholes, Warren says: "Dude, don't be a geek". This however might be just a coincidence, since it's what comes up if one changes their keyboard layout to Russian and types "USSR".
Buffy received a phone call from Angel. Having learned about her resurrection, he wished to speak with her, so Buffy left to meet up with him. This meeting was the subject of Jane Espenson's comic Reunion.
After receiving the phone call from Angel, Buffy says they won't meet in Sunnydale or in L.A. "Somewhere in the middle," was a nod for the fans, since the WB would no longer allow crossovers after they cancelled BtVS and it moved to UPN for its final two seasons. WB would later relent, allowing David Boreanaz to guest star in the last two episodes of season 7, for the trade-off that Alyson Hannigan would guest star in season 4 of Angel, during the Angelus returns arc.
The Trio attempt to bribe the M'Fashnik demon by offering to repeat some of their exploits from previous seasons:
- Warren Mears offers to build him a robot sex slave, as he did in I Was Made to Love You (2001) and Intervention (2001).
- Jonathan Levinson offers to cast a spell to make the demon "seem cool", like he did for himself in Superstar (2000).
- Warren taunts Andrew Wells about the hellhounds that attacked the Sunnydale High prom in The Prom (1999). Andrew points out that his older brother Tucker Wells was actually responsible for that.
- Andrew recounts his summoning of monkey demons to ruin the school play, an incident which happened off-screen (and which, we find out later, none of the Scooby Gang remember).
