“Didn't she just insult the real Ms. Quintin a moment ago?”
“This is turning into a real farce!”
...
Although Old Mr. Quintin was stubborn, he wasn’t confused. He quickly understood what was happening. Although terribly disappointed in Evelyn, he didn’t want an outsider like Mrs. Winters to ruin the joyous family recognition banquet. He ordered in a deep voice, “Don’t let her continue making a scene—have her thrown out!”
Old Mr. Quintin was highly respected, his former students numerous and successful. There was no need for security, nor for Gabriel or Estelle to intervene. A few men in sharp suits immediately stood up and blocked Mrs. Winters, their voices cold: “This is the Quintin family’s reunion banquet. It’s not for you to make a scene. Leave—now!”
Mrs. Winters was mortified, wishing she could crawl under the floor. She hurriedly apologized to Old Mr. Quintin, stammering, “Old Mr. Quintin, I was deceived by this impostor—I truly came here with the best intentions.”
She turned back to Sylvia, her previous attitude of contempt and aggression now replaced with pleading and ingratiation. “Sylvia, I really was misled. If only you had told me sooner, we could have avoided all these misunderstandings! Does Eugene know? I’ll call him right now!”
Gabriel said coldly, “Get security. Show her out.”
A few of Old Mr. Quintin’s former students, along with security, pressed Mrs. Winters toward the door. “Out, out!”
All the while, Mrs. Winters kept apologizing pitifully as she was pushed toward the exit, and the other ladies who had come with her were also ushered out.
Back in the banquet hall, Evelyn’s hair was in disarray, her face marked by several fresh scratches. In tears, she looked to Old Mr. Quintin. “Grandfather…”
Old Mr. Quintin replied heavily, “Today is a joyous day for the Quintin family. I don’t wish to argue about any of this right now. Go find a quiet place and sit down.”

Now he needs to boldly claim the only woman he loves is Emily…I just had to add my two cents (he he he)....
