Morty stood, fidgeting with his hands as he waited for signs of life from the apartment. For a moment, he wondered if Rick was home at all. He had done some research, poking around at this dimension before he decided it would suffice. He knew where Beth, Jerry, and Summer were - exactly where they were supposed to be. He knew Rick slept for most of the day, and concluded that he rarely left his apartment aside for booze. Rick had to be home.
The fourteen year old watched his hands shake, and jumped when he heard a voice coming from inside. He immediately perked up, straightened his coat, followed the footsteps as Rick approached the door...
It was too late to just portal away, right?
Morty's eyes widened as he caught sight of Rick. He looked him up and down. As rational and scientific as he tried to be, Morty still couldn't keep his emotions away. It had been quite a while since he stood before Rick. And it took all his willpower to tell himself that, no, this wasn't his Rick. Excitement, fear, sadness, heartbreak...It all flooded him. He inhaled a deep breath through his nose.
"Um, h-hello! I mean, um...Hi!" Morty forced a smile, but it fell the second he looked Rick in the eye. "O-Oh jeez. I should have practiced what I was going to say." The confidence he tried to show faltered into an anxiety-riddled stance. He darted his gaze to the ground, then to his feet, then back up at Rick. He forced a small wave.
"Oh right, you don't, uh, you don't know who I am." That would be the best direction to start. He straightened his posture. "My name is Morty Smith. I'm from Dimension Z-217. I'm actually, uh... You're my grandfather. Wait, no! Not...Oh, jeez. Not you personally. But." He rubbed at his face.
"I really should have put something together for this." It'd be an absolute miracle if Rick hadn't already slammed the door in his face. "Let's just start with... I'm Beth's son. And I want to help you reconnect with her and her family."
