When Giles is at the airport ready to catch his plane for England, Tara gives him (as a goodbye gift) a little plastic finger monster which she puts on her finger and says "Grrr... argh". This is the same monster and sound that is made at the end, just after the credits, by the production company mascot Mutant Enemy.
Alyson Hannigan, who is an animal lover, found the scene where Willow kills the deer difficult to film and was very upset about it.
We see Willow wearing a shirt with a number on it. We then see Xander come in wearing what looks like a football jersey with a number on it. Later when they gang is saying goodbye to Giles, Dawn is wearing a shirt with 07 on it. The crew got many letters asking what the numbers were supposed to mean, but there was no connection. Executive Producer Marti Noxon said that this was completely unintentional and was just a wardrobe coincidence.
Originally the scene with Willow killing the deer had a pan up her very bloody dress, but most of that pan was removed before the episode aired.
Spike's protective stance over Dawn is a reflection to his inability to fulfill his promise to protect her in The Gift (2001).
