Brain's death was the saddest thing I've ever seen. I even cried a little when Chase figured out Kiriko loves Shinnosuke. Some many feels!!!

Side note, I kind of found it funny that Shinnosuke and Kiriko are Mr. Belt's OTP

Brains death has to be the first death in kamen rider that made me shed a tear. He may have been a bit annoying at times but in the end he did a noble deed. R.I.P brain.

Other than that I loved the episode especially the whole kiriko denying her feelings for shinnosuke and chase being like I can see straight through your bullshit.

This episode was soooooo sad. Brain was probably one of the funniest villains ever. I'll miss him. I really wish he could've fought with Heart and Medic in the final battle. Next episode will be even sadder with Chase.

Did anyone else notice Chaser's eyes kept on changing eyes from a light orange to a red orange during the end?

Yeah that's happened a few times in previous episodes. It might be because suit actors use two different helmets: one for fight scenes and one for conversations. That could be the reason, but why the compound eyes are different colours, I don't know.

I looked through the whole scene and I dont see where they change a whole lot. They look pretty consistent to me.

They actually did change if you can really distinguish the two colors well. Go to the Kamen Rider Wiki and look at Chase's page, it has an image comparing the compound eyes.
