If I’m not mistaken, Belle and Shawn left Days. When Belle returned, she returned as a lawyer, but without Shawn. For some reason I do remember it was because Belle had cheated on Shawn. Then she jumped in bed with Phillip.
But Phillip at that time you had brought up wasn’t her professor, now was he? So why was it a necessary to bring up a non-existent professor that Shawn had brought up that had Belle slept with when according to bing-chat there was no professor at all, now was there?
