After the incident at the beach, she managed to avoid Mark for an hour by playing in the water with Dennis. Ellis called them back up the beach to eat some sandwiches that Jane had prepared, and she reluctantly followed her bother up the beach. Mark winked at her as she approached which she pretended to have not seen. Richard offered her a towel which she gladly took and wrapped up in. She then got involved in a conversation with the parents and managed to ignore any smirks and gestures Mark sent her way. She hoped he wouldn't catch on or take offense to her sudden change in demeanor, but when she finally caught glance of his inquisitive gaze, she knew her ignorance towards him hadn't been quite unnoticeable enough. She brushed it off and finished eating before standing up again.

"I'm going to head back to the house." She announced glancing at Mark.

"Are you okay, Meredith?" Carol asked.

"Yeah, I'm fine. I just have a few things to take care of today."

"Okay. Does anyone else want to head back now? We're going to stay for a few more hours." Carol told the three guys and Dennis. Dennis shook his head and happily continued with his sand castle. Derek and Burke, who were helping Dennis, declined as well, but Mark looked hesitant for a second.

"I think I'm going too."

"Whatever." Meredith said with indifference hoping her parents or anyone else wouldn't question her lack of resistance in the situation. They didn't and allowed them to trudge up the beach. Meredith stayed ahead of him and told herself it was just to throw of any suspicion their parents might have to what they would do once they got home. But at the same point she had a nagging feeling that it had to do more with what she had told that guy on the beach. Either way, he didn't catch up with her until she was at the car and putting her beach bag in the trunk.

"Hey." He sighed with a smirk.

"Hey." She replied but didn't look over at him as she shut the trunk. The ride home was silent, and as soon as she pulled the keys out of the ignition she was out of the car and heading towards the house. He followed slightly perplexed by how quickly she left him.

"Are you okay?"

"Yeah why wouldn't I be?"

"You seem like you're avoiding me."

"I'm fine. I just…" She sighed. "I'm going to take a shower."

With that she walked up the stairs. He heard the bathroom door shut a moment later. After a few moments of contemplating, he followed. Without hesitation, he quietly walked into the bathroom and began stripping his clothes off. When he pushed the curtain back, she let out a yelp and covered herself with her arms. A small smirk played his lips as he stepped in, pulled the curtain shut, and press his lips against hers. At first, she didn't react then welcomed the kiss as he pushed her back against a wall.

They didn't get dressed for a long time after getting out of the shower. They lied in her bed wrapped in each other's arms. They didn't talk. They just lied there lost in their own thoughts. His fingers played with the wet ends of her hair as she drew circles on his toned stomach. They both knew they should part ways and get dressed as to not throw suspicion on themselves when Derek and Burke returned from the beach at any moment. But they stayed as they were in each others' arms.

"Should we talk about this or something?" Meredith said quietly speaking more into his chest.

"What's there to talk about?" He asked without pausing his fingers movement through her hair.

"This morning we decided we had to… define us." She said unsurely. "I don't know how to do that."

"I'm not sure either."

She sat up a little tucking her feet underneath her. Biting her lip, she wasn't sure exactly want to say. "Earlier, at the beach, I told this guy that you were my boyfriend." She quickly admitted still unsure if she should have. A smirk appeared on his lips as he pulled her back down on top of him.

"Then it already seems as though you've defined us."

She giggled as he kissed her neck then planted a kiss on her lips. She looked down at him intertwining her fingers with his as his other hand moved down her bare back causing shivers to run down her spine. "So you're my boyfriend?" She clarified.

He kissed her again as he rolled on top of her. "Yeah, I'm your boyfriend." He told her between kisses.
