If what's true? Potential rape?
Possibly :-(. And if that's true Richard, the most despicable member of the Horne family now, was likely the byproduct of it :-(.
On the other hand....Dr. Jacoby revealed that Audrey was comatose after the bank vault explosion. Imagining EvilCoop having non-consensual relations with a comatose woman, who then gave birth to a son, sound a bit too far fetch to me.....
Why would the ring be in the ICU?
We hadn't seen it since Laura...and since it didn't actually exist in the show.
As Sammy says, it's in FWWM and it actyally exists in the show. It just doesn't show up on camera: aka, the "golden circle" Philip Gerrard/MIKE talks about when he describes his relationship with BOB, and it's referenced in the 'clues' BOB leaves behind in his victims' ring finger (save for Laura who had to be killed because of the ring, and not because BOB wanted to do it).
In the missing pieces we see the scene where Annie is left in the ICU and she re-lives the scene in Laura's dream: she grabs the nurse's arm and goes "My name is Annie. I've been with Laura and Dale. The good Dale is trapped in the lodge and can't leave. Write it in your diary.", then faints. The nurse gives a WTF look, then checks the ring out and steals it. She goes to the mirror and sees how her new acquisition looks like on her finger.
