That said, Devine was understandably disappointed with how her time on the hit medical drama wrapped up.

“That’s why you just have to keep going,” theGrey’s Anatomyalum wisely reasoned withPeopleTV.

“When you go down, you’ve got to just get right back up and keep moving.

Because you’ve got the option to’t understand why stuff happens in this business.”

“Then she came over there toGrey’s Anatomy, took over that, then I was gone.”

She added, “I love Debbie Allen, but the truth is the truth.”

All kidding aside, Devine has been working pretty much non-stop ever since.
