Ela and Lesion were assigned a mission to investigate terrorist activities in Poland. After their mission was complete, they had some downtime for themselves. Seeing how Liu handled everything out of the playbook in style, she had developed a strong interest in him. Once they returned to Ela's safehouse, Ela herself went to undress and shower while Liu debriefed with Six. After that, Ela had already finished showering and noticed that Liu hasn't showered yet. She then decided to give him some stress relief. She didn't know how to, but she wanted him to be the first.
