Instead, Haley felt like the Joker had been… testing her, when he touched her cheek.
In fact, Luke was indeed testing the feel of her skin.
This was the first change which the symbiote caused to the physique.
Selina had formed a symbiotic relationship too early. She was someone he knew, so he couldn't do anything to her, much less treat her as a test subject.
So, Luke simply took advantage of the fact that he wasn't familiar with this female doctor to get all the data he needed.
In any case, she had already been given the symbiote, and it came with a high-paying "job." There was no need to let it go to waste.
Luke got straight to the point. "Pack up, we're heading out."
Haley perked up. "Where to?"
Luke said, "New York."
Haley was baffled.
The female doctor was soon ready, and the two of them took a plane to New York in the light of the setting sun.
