Jake knew that Todd wouldn't be able to fulfill what the doctor suggested as his mother had always regarded him only as a friend.
As for grandmother and Mary, they were both Wendy's seniors who loved her dearly, but they weren't the best option.
Leah was one of the people who Wendy cared about the most, but she was too young to be up for the task and might just end up crying. Jake himself was more strong-willed than Leah. But eventually, Jake still put his best hope on Michael. After staying silent for a while, he said to Michael, "Dad, why don't you go?"
Michael missed a heartbeat when he heard Jake call him 'dad'.
He only asked Jake to call him that in the warehouse when he was dealing with Yvonne, and now, having heard Jake call him dad voluntarily, he couldn't help rejoicing, even though it lasted for only a millisecond.
As for Jake, he wouldn't ask Michael to try if he hadn't approved of him.
