Two weeks before Barry got put in jail, it was just a "normal" day at Caitlin Snow's house when all of a sudden a breach opened in her bedroom while she was folding clothes which nearly scared her into being Killer Frost. All of a sudden she saw a lightning trail which meant it was a speedster coming out of the breach, she prepared herself just in case it was an evil speedster but out of nowhere the speedster and started kissing Caitlin. When the speedster stopped Caitlin saw that it was Jesse from earth-2 she was smiling. Caitlin was confused "Wha-what was that for?" Caitlin asked smiling too "Ever since I met you I saw that you're beautiful, smart and funny...dating Wally was just a distraction cause I didn't want you to know...but whether you're Caitlin Snow or bad ass Killer Frost I will always love you." Jesse said with joy and happiness. Thy both smiled at each other and started kissing again, so then from then to now Caitlin and Jesse had been dating although when things got heated Killer Frost came out and things got "bad ass", Killer Frost wasn't afraid to get rough and Jesse loved that.

The two never told anyone about their relationship, while the others were off fighting DeVoe the two were planning their "secret' wedding. Th only people at the wedding were the women in their lives, such as Sara Lance who asked if she could bring her girlfriend Ava Sharpe and they agreed, they also invited Speedy, Felicity, Caitlin contacted Kara Danvers to see if her and her sister were available so they came and Iris. So of course as you can tell this as an all women wedding, Caitlin or a frosty blue dress while Jess was in the other room putting on her red tux with a yellow tie. After the wedding they all partied in earth-38 at Kara's apartment where they stayed til the next morning.

Once they got back home to earth-1 Jesse decided to stay with Caitlin at her house. Jesse heard from Caitlin that Iris told the team about the wedding. Caitlin got worried and scared and turned into Killer Frost, the two stormed off to S.T.A.R. labs and explained everything and honestly none of them cared they were just happy for them.
