Justin questioned Donna about her sudden disappearing act in high school and she tried to cover, apologizing for the pain she'd caused him. He thanked her for that, shrugging, "We were kids. What did we know?" Then, he asked about her life now. She talked about Eric and her mom's Alzheimer's. Justin envied her close family connections but noted his life had turned out for the best. Donna fished for personal info and Justin revealed he's divorced and childless. As for her, Donna noted Eric already has two families...and then Marcus walked in! Donna tried to introduce Marcus all casual-like, without giving away he's her son. She looked on like a deer in headlights as Justin and Junior shook hands and made small talk. Then, she hurried Marcus out the door and made her goodbyes to Justin. "There's a part of you that'll always be with me," he murmured. Their gazes locked before he left. Alone at Spencer Publications, Justin did a little research on Forrester. Meanwhile, Katie made distracted Donna jump out of her skin and she admitted Justin had been by -- and met Marcus! "It was actually beautiful...and frightening," she admitted, talking about how wonderful Justin still is. She was terribly confused about what to do, noting that Marcus seemed disinterested in meeting his biological father. Donna hoped Justin would go back to NY and this would be a moot point. However, Justin kept researching...and stumbled upon the news that Marcus was Donna's son, whom she'd given up for adoption as a teen. He reeled, murmuring, "Could it be? Is Marcus my son?"

Stephanie dropped by to visit Eric, who told her that he was adopting Marcus. Katie walked up on Marcus playing basketball at the Sky Lounge, and they shot a few hoops. Bursting with glee, Marcus told "Auntie Katie" that he'd found his father. Katie was taken aback, but it quickly became clear he meant Eric. Back inside, Stephanie boggled at the idea of adopting a grown man: "Have you really thought this through?" Eric assured her he has. Stephanie noted he might face opposition from their kids. She warned him that they might not be one big happy family. "Please don't cause any problems," said Eric, noting how much he wants Marcus to be a Forrester. After he left, Stephanie got a little woozy and disoriented and lost feeling in her extremities.
