some of the other questions to address are:
1) Who did Becker's (the antagonistic death row prison guard) son shoot at the end of the episode?
2) (As mentioned in santiclaws' thread above) Why did Holder's new "partner" have a large bandage on his hand when Holder was beating him down?
3) Why did Linden tell Skinner that "she was wrong" and there was no link to Seward's wife's murder with the other murders? The reason I ask this is, even though she couldn't put any PHYSICAL evidence to link the crimes together, she STILL has Adrian's confession AND his drawings of where the bodies were found? How else would he have known that?? Wouldn't you still consider those to be "links" to the murders?
4) Danette tells Linden that Joe was in Alaska for 3 years, and so he couldn't have been in town the night of Seward's wife's death. Oh really?? Since Joe's such a reliable, honest guy, she just took his word for it that he was in Alaska the whole time?
5) The other thing that irked me (and I saw on other discussion boards) is that, Bullet wouldn't be dead had she just SAID ON HER VOICEMAILS to Holder WHO the killer was, by name. That is, assuming that the killer wasn't Holder's new "partner", and she felt uncomfortable telling Holder that unless she could say it in person?
6) What's the deal with Twitch? (is that the dude's name dating Lyric?). There sure are a lot of red herrings surrounding that guy (and not just because Seattle is known for its seafood at Pike Place Market! Ba da bing!). Is it possible that, Twitch might've been the one who got shot at the end of the episode? Or maybe Skinner? Most likely, it wouldn't have been a stranger, but instead, someone Becker's kid knew. Is it possible that, Twitch is involved in these killings? Or how about Skinner?
