I finally finished watching Season 11 and am now going to the last season.
[Season 11 spoiler alert (You have been warned)] Honestly the last episode of season 11 freaked the hell out of me. All those nightmares were soooo freaky!! >_< Episode 13 (The monster in the closet) had already been creepy enough but episode 22 had me hugging my Gintoki bolster the whole time... orz
And as much as I loved Zack in season 1 (he was sooo cute), and I knew that he was coming back in Season 12, this was definitely not how I expected him to come back.
Like what miyabi_kkg said, season 12 is going to be so painful to watch...
I'm not sure what to expect, but I'm guessing there's going to be lots of mourning for Sweets, and painful times looking at Zack 黑化... >_<
On another note, the end of episode 21 (The Jewel in the Crown) had me tearing up when Daisy pointed out to Hodgins that he may have the chance to walk again. And the muscle spasms that Hodgins is suffering in episode 22 is actually similar to what dad is experiencing recently, though not as painful as what Hodgins is experiencing. Hopefully that means that dad is on the way to a more complete recovery?
