Marty watched as the other ascended up the slate grey steps leading into the Hill Valley High School - now temporarily the Expo and inhabited what Marty assumed to be a real mess in there. Emmett's brief description of the 'broken glass' and the screams Marty heard minutes ago could only picture just how much trouble the young budding scientist was in. To add to that, Judge Brown's voice constantly booming, incessantly calling for his dear son.
"Wait..." He stopped in his tracks. He spun on his heel, turning towards the other. The sudden thought appeared in his head; was this a good-bye? Would I see Marty after this? It seemed like there would be no other reason for his newly-founded mysterious friend to return to him.
"I... will see you again, right?" His brows furrowed slightly, faltering. Vocalising it contorted his expression to despair. He wondered if it was too visible on his face because Marty seemed to have picked up on something somewhat.
Marty's lips parted at sudden but inevitable question, as it has also dawned upon him that farewells - fortunately for Marty, it wasn't but for the younger Emmett, it did seem like so. He swallowed inconspicuously.
"I... Guarantee it." he responded, though he had felt sure that it was a possibility that he might not be able to follow up on that. If there was no excruciating and consequential disaster that had occurred in the future as a result of him being here, changing the course of the people of Hill Valley's lives - or worse, causing either him or Doc to begin fading out of existence - then he wouldn't need to back to meddle with 1931 any more.
Emmett continued looking back at the other. Despite Marty's somewhat reassuring words, he was still feeling something.
If this was a final good-bye, then it can't be like this.
Following heed on his impulse, he rushed down the stairs with a very adamant lack of care - which could have ended embarrassingly disastrous - and dashed towards Marty who had been standing there.
It all had happened so quickly but before he had realised it, Emmett had smacked his hands to the back of Marty's head, yanked him forward, tilted his head upwards to angle better to his face and hastily pressed his lips against the shorter's ones.
It could be paralleled to Edna and his' first kiss - quick and inexperienced - but a lot less gentle and with more pressure than their brief touch.
He hadn't last long enough to allow the other to deepen it, only grabbing a few locks of Marty's soft hazel hair before letting go. As quickly as he pulled in, he pulled away and parted and, without looking back, he dashed back up the steps and through the double doors, repeatedly shouting "Coming, Father!" as he scrambled away, face flushed.
All the while, Marty had been left there completely dazed, but oddly pleasantly surprised. He lifted his fingers to his lips, feeling the trail of saliva left there against the skin on his fingertips.
Heavy.
- "...Goodbye Emmett." he muttered, lamely holding a hand up to wave in the direction that Emmett had left in, seconds before he was shook to reality by the familiar booming sounds of the Delorean blasting inches in front of him.
