Caitlin tries to wake up her left side by punching her arm. That's when she realizes she only has one eye open. WAKE UP NOW! Caitlin tries to yell, which causes her to finally see out of her left eye. "What is going on?" They both ask in a semi-frost, normal human way.

Caitlin staggers to her feet, causing a splitting headache. Unable to use her entire left side, Caitlin clutches her forehead. "What is going on?" Frost asks in her head. "I think-" Caitlin musters with only half of her mouth before the headache happens again. "I think that headache caused us to merge together. Like both of us are in control of one half of our body." Caitlin tells frost in her head. "You are joking." Frost crackles in ice. "We need a mirror." Caitlin says in her head. It's an awkward sight as it appears that Caitlin is learning how to walk again. Each time the two don't agree on anything, a splitting headache emerges.

"This can't be happening." Caitlin says in a Two-face kind of speaking. It turns out that headache caused a break in the control and now both Frost and Caitlin have access to their body. Caitlin could not open her jaw and only said something using her lips. "We are perfectly split down the middle." Frost adds, using the other side of the mouth but no jaw. The right side of the body is Caitlin, who has her normal skin tone. The left side has Frost with her pale, cold colored skin and blue lips. This looks really weird from an outsider's perspective.

"We need to agree on doing things together, or the entire team is going to think we did something crazy," Caitlin says in her head to avoid the really strange way of talking with the use of only half of her mouth, "Otherwise we are going to collapse again and pass out with a splitting headache." "I hate team effort." Frost coldly says, again with the side of her lips. "Would you prefer that massive headache again? I would like to use the lab's scanners to see if my theories are right." Caitlin says, in her head this time to avoid the debilitating headache. It's really strange to see the body of Caitlin trying to leave the bathroom area. Both can move their individual eyes independently of one another, which does not cause a headache. Even their hair is perfectly split frosty white and Caitlin's brunette hair.

"Now you can have your side of the body with the hair over your shoulder, and I can have my hair down my back in order to see properly." Caitlin says to Frost using their shared minds. "Let's just focus on getting the team to figure out this issue. I want to know what is going on without causing a massive headache again." Frost replies.

The Caitlin/frost mashup manages to walk into the cortex. "Ok, that is a Dragon Ball Z fusion gone wrong if I ever saw one." Cisco jokes. "What happened?" Barry asks. "That is- Ow!" Caitlin groans due to the headache. We need to say 'That is why we need your help to figure this out' together or we are going to pass out again. Caitlin tells frost. "That is why we need your help to figure this out." They both say together, both frosty and in Caitlin's normal voice.
