In the Crimson Halls of Kane Hill: Season 1, Episode 4

WARNING: If you don't want to know what happened in this episode, don't read this photo recap! 

Okay. So, Grace wants to save her sister from Heart Industries, Aki wants obedience from Christopher at Heart Industries, and Arthur wants to take down Heart Industries all together. Caught up? Good, because it's day four of the Blood Drive.

In order to sneak off to save her sister, Grace made a deal with The Scholar to mess with Julian Slink's brain-bomb remote control. When he finds out, he's pretty upset.

Grace and Arthur head off to the Kane Hill Mental Hospital - run by Heart Industries. They find, instead, that the whole staff (and the inmates) are addicted to candy that's made them all even more insane.

It turns out (in flashback), that a few years back, Grace took her sister to a rave so she could find a way into the Blood Drive. This was before she knew that the Blood Drive had actual BLOOD in the cars. There's still some guilt…

Meanwhile, Julian has sent Jaw Bone out after Grace and Arthur. Well, mostly Grace. He doesn't care if Arthur comes back alive.

Arthur meets a nurse that tells him what went down here. On Halloween, there was an uprising in the asylum once all the inmates got hold of the candy. She convinces him to lose the cop outfit so they can escape and he can restore order. She explains that the asylum is being used to test highly addictive candy.

Checking in with Christopher, Aki has really started to go to town on him. She's starting to collect a bunch of fluids. Saliva, and…more. It's gonna get serious, team.

Grace catches up with her sister's doctor, but he's in rough shape. An inmate kills him just after he tells Grace that she has to stop them all. In the process, she starts a fire in the asylum.

As Jaw Bone convinces the inmates to bring him Grace and Arthur, let's all flashback to that party. Turns out, that's where Grace's sister started doing Red. The drug that's really messing people up.

After Grace learns that her sister was transferred, she tries to get the records. But instead, gets drugged with Red by Jaw Bone. It turns out, that drug makes you nuts, and that's what got her sister locked up in here in the first place.

And it turns out? In a flashback: Outside the asylum where she locked up her sister — is exactly where Julian Slink approached Grace about the Blood Drive.

After a pretty intense fight with Arthur, Jaw Bone meets his end as the inmates devour him. (Covered in that candy, see.)

Grace and Arthur blow up the asylum and escape!

And Aki gets the last fluid (there were more collected, but…) — a single tear.

And finally, Grace and Arthur learn that not only is Heart Industries behind all of it - Julian Slink is the connection they hadn't fully considered.
