The health scare results in Kate and Toby growing closer, and Sullivan offered a hint about what the future holds in store for the couple.
“In my experience, that type of life-changing experience can push people in two different directions,” he said. “It can push people to shut down and to go inward, or it can push people to appreciate the life that they’ve been giving.
“Over the next few episodes, knowing Toby, he’ll probably dive in a little deeper into appreciating life and everything that he has,” he added.
And since the “M-word” came up, might there be a wedding soon for the beloved pair?
“I wouldn’t be surprised,” Sullivan told “ET.”
