A/N: In my mind, this story is a "missing episode". I am a fan of Chlark from way back (thought they had great potential), but also enjoy Chloe and Oliver together now. This story deals with both relationships as they are around Escape (the last episode I watched of Season 9), though I'm generally aware of the plot for the rest of the season. The story jumps around a bit in time (and universes), but I'm trying to make it easy to follow.
Our Universe, Present Time
"Chloe!" Clark shouted, running into the Watchtower. "There you are."
"I'm always here, Clark," she frowned, turning back to her computer. "What's up? Is there something you wanted?" She was acting a little cold, he thought.
"No," he said, coming to stand behind her. "Nothing specific, just wanted to see you." He put his hands on her shoulders, frowning when she tensed up.
"What's wrong?" he asked, turning her to face him. She looked up at him, confused.
"Nothing," she said, backing away slightly. "But I'm starting to think there might be something wrong with you. After you feeling okay, after yesterday?"
He looked at her strangely. "I'm fine. I just feel a little strange today," he said, smiling. "I feel better now that I've seen you."
She raised an eyebrow at him, but smiled back. He took the opportunity to lean in for a kiss, but just as he was about to touch her lips she shoved at him and screamed, "Clark! What the hell?"
His eyes widened with hurt. "I knew something was wrong!" he said, looking down and noticing her bare finger. "Where's your ring?"
"My ring?" Chloe asked, sidestepping him to put some distance between them. "What does this have to do with my ring?" He took a step forward only to have her take another one back.
"Why aren't you wearing it?"
"I haven't worn it in a while, Clark!" she said, eyeing him warily. "Didn't you notice?"
"What?" he said, angrily. He was sure she had been wearing it yesterday, but he guessed he hadn't specifically noticed it. "Why not?"
"Why do you think?" she said with eye roll. "With everything that happened…" she trailed off, looking away. "Plus, Ollie wouldn't like it very much," she finished.
Now he was confused. "Oliver?" he asked. "Why would he care?"
She looked at him like he'd grown two heads, then narrowed her eyes. "Clark, I know that the Irish B & B incident was a shock to you, but don't tell me you repressed it completely."
"Irish B & B? You mean the place we went last month?"
"Yeah, evil succubus killing men, Ollie almost getting killed…" She said in a slow, 'teacher' voice.
"I remember," snapped Clark, moving closer to her. He was relieved when she didn't back away.
"Well, Ollie and I aren't exactly together, but I think he would mind if my ring scratched his back while we were… being intimate."
At that moment, Clark saw red. "You slept with Oliver!" he shouted.
Chloe pierced her lips. "Clark I realize that you're an old-fashioned guy, but not everyone has a holier than thou attitude towards sex."
"You slept with Oliver!" he repeated in a hurt tone, eyes watering.
Chloe's face softened. "I know you don't agree, but it's my decision to make. I'm moving on."
"How could you do this to me?" exclaimed Clark, looking at her with wide eyes.
"Clark, this isn't about you," she said.
"How is this not about me?" he said. "I wake up to find the bed empty, and after having the most bizarre conversation with Lois, I come to make sure my fiancée is alright only to find her without her engagement ring on, telling me she slept with one of my friends."
Chloe was stunned into silence. "What? Fiancée? Engagement ring? Oh my god... The accident yesterday." Realization dawned on her. "Clark, this is going to sound crazy, but I think you're in the wrong universe."
