Jealousy

 After playing with the ball in his hands for a couple of minutes and seeing that Roselyn was almost done with the dishes, he decided that's better to tell her what's on her mind, rather than keep it to himself, that's not good for their relationship, he wants to fully trust her with no doubts in his mind or heart. 

 "What were you and Jack talking about?" Jonathan asked, squeezing the ball in his hands, a bit unsure of what Roselyn's reaction would be, considering that they told one another they would trust each other, but he found a bit of difficulty in that when the person in question used to like her.

 "About what we all talked about earlier, homosexuality." Roselyn replied with only that since she didn't want to reveal everything that Jack told her, she wanted to keep it as vague but truthful as she can, but that got harder as Jonathan continued to ask questions about it.
