When Michael brought Leah back to the hospital, he had to suppress his emotion on purpose to maintain his composure on the outside.
Jake wasn't worried if Michael would do anything to Leah. He was only worried that Michael finds out that Leah was his daughter.
To Jake, he had already approved of Michael as his father. So, Jake thought it would be good if Michael found out the truth.
However, he thought of how his mom had yet to recover her memory and his mom had always wanted to hide the fact that Leah was Michael's daughter from Michael.
Hence, Jake had no choice but to consider the situation, putting himself in Wendy's shoes.
Leah took out the toy that she picked up for Jake. Then, she handed it over to him happily, saying, "Jake, I picked this just for you."
Jake accepted the toy and said thank you.
He stopped playing with toys long ago. But seeing how delighted Leah was, Jake didn't want to be a party pooper.
