Ellie and dina have been married for two years now. Jj was like Ellie's son, even though he wasn't biologically.

You were Jj's babysitter, you'd take care of him when they couldn't. Ellie has always looked fine to you, the green eyed girl thought the extact same thing about you.

That's how you ended up with Ellie's hand on your mouth in the bathroom, Dina was home. This thing has been going on for months now.
