Buffy the Vampire Slayer

The Initiative beginning when Spike mentions the Nazis is more than likely because in the episode "Why We Fight" on season 5 of Angel during WW2 he was drugged by the SS.

After Harmony and Xander have their cat-fight, Harmony lights a match to throw onto Spike's things. While she is talking to Xander the match burns out, but in the next shot the match is still lit, as she throws it onto Spike's things.

The vampire that warns Spike about the drugged blood is the vampire that was captured at the end of the episode "The Freshman."

When the Initiative scientists are taking Spike out of his cell the empty blood packet can be seen. Spike didn't drink the blood as he's only faking being unconscious. The cell has no toilet or sink, and there isn't a drain in the floor. It's not clear what Spike did with the blood.

When Graham is scanning the various body temperatures, they're ALL 98.6°, except for Spike. While 98.6° is roughly average, peoples' temperatures will vary by a degree or two as a matter of course; the chances of finding three people all at exactly 98.6° is pretty slim. Then, when he gets to Spike, Spike reads 62.3°, which Graham announces is "exactly room temperature". First, there's no such thing as "exactly room temperature", as different standards put it at different temperatures, typically varying from 68 to 77° Fahrenheit. Second, a temperature of 62.3° would be noticeably cool, and would not be considered a normal room temperature, much less "exactly room temperature".

Spike and the other vampire cast reflections in the glass of the Initiative's holding cells.

Spike states that he is 126, yet in the season 2 episode School Hard Giles says that he is "barely 200." Also in the upcoming episode Fool for Love" we learn that Spike was sired in 1880. If he were 126 in the year 2000 it would mean that he was 6 years old when he was sired, yet he appears to be between the ages of 25-30.

At the beginning of the episode when Spike is in his cell and the camera pans to show a never ending row of cells, you can see the mirror used to make this effect possible.

Giles' drawing of the commando guy was pretty good, but a few weeks later, in Hush, his drawings of the Gentlemen are a little less as artistic. It's the same thing with the drawings's he made for Chao-Ahn in season seven's "First Date". How'd he go from so good...to not-so-good?

Maggie Walsh calls a Code Red and reports that Hostile 17 (Spike) escaped at 2:47 pm, yet she did not call Riley's team until many hours later. Also, she uses regular time rather than the military 24 hour clock.

When Spike examines the dorm room assignments on a computer, there does not appear to be an order for the names. Although they are grouped by first letter of last names, the first names are random.

If Spike has had a chip in his head since before he woke up, a chip that prevents him from harming humans, how was he able to fight his way out of the Initiative? Throughout the episode, Spike actually does a good deal of fighting without the chip going off, not just when he escapes the lab, but also when the soldier boys try to bag him in the dorm and he tosses them around. It only really goes off when he tries to bite people. A possible, albeit weak, explanation is offered near the end of the episode, when Riley is reporting in. He says that "Hostile 17 can't harm any living creature...". The key word there being "harm". The possibility of at least hurting someone seems to be confirmed as expected behaviour, when Riley continues with "...can't hardly even hit any more." If he couldn't hurt any living creature, then hitting would be unexpected; but if the limitation is harm, then hitting would still be possible.

When Spike has Willow against the wall in her dorm room, he vamps his face out. At this point, when Spike has his back to the camera, his coat collar is up, but down when it's facing him, and so on as the camera cuts back and forth a couple of times.
