i'm pretty convinced walt is the guy that done this. the main tip off for me is walt and camera both focusing on the plant which is obviously a weakness as brock is primarily rock type.

If it turns out that Walt is somehow responsible, I'll probably be fine with it. There were a few brief facepalm-filled seconds where I seriously thought they were going to say the kid ingested it by smoking the cigarette.
Also, when watching the end of the prior episode with Walt losing his shit in the crawlspace, I had a really stupid stoned thought that Walt might be in the onset stage of Huntington's Disease
edit: I actually forgot about that Dexter episode. Some genuinely funny parts, some considerably boring, and a whole lot of ham-fisted religious crap. Still can't be worse than last season! I'll keep watching for Michael C. Hall and Edward James Olmos.
I also finished Terriers. Great show. Not much else to say. I would have donated to keep it on the air
All caught up on Childrens Hospital.
Working my way through Party Down.
