Many thoughts flashed through her mind, and in the end, she just said, "I'm fine now, I have to go first."
Perhaps when Tommy's illness is cured, and she's finished dealing with Robert Thomson, or maybe compensating him with money or something else...
She tidied up a bit.
After all, when you're in the hospital, you have to wear a patient's gown, which wasn't possible when she was with Tommy.
So, she first found a mid-level floor, went into the women's restroom, changed into a new patient gown, fixed her hair, and then left.
Back in her own hospital room, her current condition didn't actually require hospitalization. However, she wanted to take care of Tommy up close, and Robert was afraid that once she left the hospital, she'd be bombarded by paparazzi.
Once everything was done, she sneaked back to her room, and Robert hadn't come yet.
