(EXCLUSIVE) Toya Harris & Quadd Webb Go AT IT Over Dr. Eugene During 'Married To Medicine' Reunion Finale, 'Why Do You Hate Us?!'

Remember when Quadd called Toya's husband Dr. Eugene Eu-GYNA on social media? Yeah, they didn't sit well with Toya or Eugene. And they finally have it out on the upcoming "Married To Medicine" reunion finale. We've got an exclusive sneak peek inside.   Things get heated between the Harris couple and Quad Webb during Part 3 of the reunion. Apparently, the former friends have been heavily beefing for quite a while now, so now that their fighting has reached a boiling point, it all exploded on the final installment of the reunion. Quadd has been calling out Eugene covering up for Toya's "behavior" and smart talk and heavy spending, saying it's driving him to be unhealthy.  She alludes to Toya being too selfish to care how it's all tearing up the good doctor, and now Toya is pushing all the way back. After Quadd called Eugene Eu-GYNA (rhymes with vagina), challenging his manhood, that was the last straw.  And the yelling ensued.  We've never seen Eugene this mad.  Which means Toya was MAD mad. Quadd's explanation for coming for them?  They came for her and shamed her about her divorce.  Watch the fireworks in our exclusive sneak peek above. Also in the episode: Kiran and Eugene try to settle the score. Scott surprises everyone, revealing a shocking career move. The women join the stage and Contessa confronts Damon.  The ladies get down and dirty as a surprise reprise from Vegas has everyone hot and bothered. “Reunion Part III” airs Sunday, Nov. 6 at 10:15 p.m. ET/PT   Photos: NBC Universal
