terwards she just lays there and goes to sleep.

She doesn’t know if he slept in the bed with her or not because “it was dark in the room.”

The next morning around 7:00am she gets up and goes home.

Juan is not there and she doesn’t know when he left.

I'd twist her up on this. Get deep into her state of mind. How traumatic was it, how could you just go to sleep, not knowing if your alleged attacker was still their etc.
You also need a better understanding of the time line. How many days afterwards did she make the statement of, "we shouldn't of done this."

Had she pre-arranged a bed or was it spur of the moment? When did she realize she was gonna stay over
Who did she tell about the alleged attack

you know the routine, start of with random questions, slip a few like "what kind of car she drove over there, where'd she park, what does defendant drive" Random questions not in chronological order. Then slow walk her through a play by play of the night.
Do they both speak engley pretty good?
