This review may contain spoilers.

Another week of “Being Human” and another week of domestic monster problems. It also means another week of flashback-Aidan (Sam Witwer) -– this time, looking very dapper in a John Wilkes Booth (or James Marsden as John Wilkes Booth in “Zoolander”) sort of way.

But other than reminding us of some of Aidan’s more daring fashion choices over the years, this week’s episode actually served mostly as the “these are the rules of our show” episode of the series so far. While the episode itself wasn’t merely an expositional info-dump, it was full of the rules for each one of the monster roommates. Some were “obvious” -- ghosts are made of energy, so they just need to focus it in order to move around -- and others were very important for future reference: The closer to the full moon it is, the more a werewolf’s senses (and animalistic nature) kicks in.

Despite all of this, “Some Thing to Watch Over Me” was the most emotional episode of the series so far. For as much as Aidan, Josh (Sam Huntington) and Sally (Meaghan Rath) attempt to be “normal,” there’s still a lot they can’t control. The only way Aidan can control his powers of compulsion is by finally giving into Bishop (Mark Pellegrino); so that’s not really an option. For Josh, all he tries to do is control himself, but even on a normal night that’s not a full moon, he can’t stop the werewolf from coming out just a little bit. And Sally can’t control the fact that Danny’s trying to move on and will probably never be open to seeing her, his ghost of a fiancé. The latter two found ways to accept this, but Aidan’s stubbornness actually worked to his disadvantage at the very end –- his self-control in his life proved Bishop right.

Points Of Interest

1. So far, showrunners Jeremy Carver and Anna Fricke have written every episode. We still have yet to see what differences –- if any -– will come from other staff writers taking the reins.

2. There was a bit of really dark humor in the scene where Tony tried to kiss Sally. Sally’s disgusted “Get out of me!” was kind of hilarious because of the ghost thing, until a second after when you realized it was still sexual assault.

3. Sam Witwer is really good at dying, isn’t he? (See also, “Battlestar Galactica” and “Smallville.)

4. Also, did anyone else think that police sketch of Aidan looked like Starkiller from "Star Wars: The Force Unleashed"?

What Worked

The Josh/Sally friendship is coming along nicely. He turns newspaper pages and threatens “handsy” ghosts for her and isn’t afraid to tell her the truth, whether she’ll like it or not. With this strengthening of this relationship and the established one between Josh/Aidan, all he show really needs to work on is Aidan/Sally.

Also, the open-endedness of whether or not Aidan’s compulsion actually worked was great. It’s completely possible that Bishop actually killed Garrity (or had him killed) to make Aidan feel guilty and have him return to “the family” as quickly as possible. Hopefully we don’t have to just take it at face value and there will be a definitive answer eventually.

What Didn't Work

The necessary exposition of the rules for these characters did seem the most clunky when it came to Aidan, which is probably the result of the ubiquitous vampire nowadays. While it was funny to see Sally pester him about things while he was brushing his teeth, if the boys’ afflictions were all they ever talked about (as she teased them about in the pilot), it seems as though she would have known a lot more about vampires than she actually did at this point. While the teaser didn’t actually do the verbal acknowledgment of the rules for vampires like most of the rest of the episode did, it was obvious when Aidan stopped to tie his shoes that the only real purpose was to answer the vampire reflection question (which has an ever-changing answer, just like the rest of vampire lore).

Another thing –- which is currently a staple of the show –- that stuck out was the continuation of the opening voice-overs. While still kinda fitting with the tone, these could possibly get overdone very quickly.
