A/N: I had no idea that this fifty drabble thing would be this…well…long. XD I've never done such a long series before, or a long chaptered story such as this period, so it's starting to get difficult for me. Especially since my mind tends to wander off to other fandoms and stories. But, I will do my best to continue this, even though my mind is about to explode due to lack of ideas. I'm sure I'll handle it. Anyway, I hope you enjoy this drabble! R&R. Enjoy!

Scent
~…~
Cade had always had a unique scent about him. It was unlike Optimus had ever before encountered, and having been created many, many long years ago, that was saying something.
Humans had, from the moment he had landed on Earth, smelled different from other forms of life he had encountered in his time. They were, obviously, very different from his comrades and kind from Cybertron. But humans were even more different and distinctive from the other forms of life that inhabited Earth alongside them. Animals, depending on species, had many different scents, all of which differed from humans. And humans each had their own scent, something that set them apart from one another, much like their fingerprints. Although different and unique to each human, they all had one underlying scent, a common thread that tied them all together as a species.
Cade was different.
He was human, Optimus was positive about that, but there was something about his scent that was unlike all of the other humans on Earth. That underlying scent that connected his species was less…prominent, not as strong or as noticeable as it was with the rest of the humans. Cade was something Optimus had never seen or scented before. If Optimus had not known better, he would speculate that Cade was…a more evolved type of human. But that would be ludicrous. Human evolution of any kind took hundreds, even thousands, of years. And Optimus could not see them evolving so much so that it would change their scent as a species.
Whatever the reason for Cade's unique scent, Optimus thoroughly enjoyed inhaling it, having it in his systems throughout the day. It was a scent that he would always remember, the scent of his spark mate, and he had no doubts that he could find it even if something happened and he became separated from Cade. Optimus knew that he had the ability to find Cade anywhere. Perhaps it sounded arrogant of him, but it was just a feeling, an instinct, that Optimus had. He would always be concerned for Cade's safety, but he would always be able to find him one way or another.
Through his scent would always be one of them, however limited it may be depending on distance and other variables, of course.
Optimus had spent enough time with Cade to have his scent saved in his spark, a permanent memory that would remain with him long after Cade passes from this life into whatever awaited him after. Thinking about Cade's limited life span caused a great sadness to resonate within Optimus, but he need not dwell on that now, and not with so much sadness as he felt. He would always remember Cade just as he would always find him no matter what. Through the bond they shared together, through sight, through scent, and through love.
