Angel

Time flows faster in the Quortoth, and Holtz took at least a couple of Earth-hours to follow Connor through the rift. Holtz would have been alone in the Quortoth for weeks, maybe even months, before following Connor's lead. When Holtz finds Connor, he acts like little to no time has passed at all, when in fact it might have been quite some time.

After the fight, Connor immediately returns to Holtz and Angel to Cordelia. Angel doesn't even comment on Connor's disappearance or reappearance.

When Angel finds Justine at the bar, he tells her to run, and she does. Why would she take advice from Angel? The reason she was at the bar in the first place was to fight vampires, so why not stay and fight them?

When the vampire that Connor is fighting escapes he follows it and then Angel follows him. In the overhead shot of them running out, a couple of vampires are visible laying on the ground and staggering to get up. It seems odd that Angel would leave those vampires there to hurt more people. He may not kill every demonic creature he comes across but since these vamps were actually attacking somone you'd think he would prefer them dead.

When Holtz finishes his voiceover, he says, "Lovingly, Your Father" but the closed captioning says, "Lovingly, Dad".

It is not explained how Justine was able to find Holtz at the motel.
