The company where Jilly was created by, and subsequently altered by Karen, is called Chemsok. I think a lot of you might remember the name from a previous universe. Now, the employees (let's just call them that) of Chemsok, have a hard time wearing heavy neoprene like suits all the time, since there is very little to almost no regards for safety surrounding spillings. Hence, these extreme conditions require extreme stress relief.
On a daily basis, the employees are required to receive either automated or mutual private moments for relaxation. This is also due to their design (why not use your own products for production anyway). Jilly being based off these Chemsok employees, has inherited these traits, which explains her behaviour a little. They also kind of look like eachother, don't they? Such an uninspired company...
