Who should be in the bottom three?

After rewatching last night's SYTYCD episode, I have formed an opinion on who I think should be in the bottom tonight. My bottom three is Caitlin & Jason, Karla & Jonathan and Asuka & Vitolio. From there I'm not sure who I would save or send home but I do think Jonathan has yet to impress and I am consistently annoyed with Asuka. Thoughts?
