Addendum:

When I originally finished this story, I had -promised- to attempt to start writing its sequel. Well, it's been nearly half a year since then - and I've only just now realized that ffnet, unlike ao3, has no real way of easily finding a fic's sequel unless you're tracking their account. So I'm adding this here as a way for anyone who reads this in the future/has read it in the past to find its sequel(s) more easily:

Currently I'm in the process of writing ONE (out of two planned) sequels, titled E-Brakes On (you can find it under this account). It is heavily a WIP & my life does not allow me much time to write anymore, but I do plan on finishing it someday - so if you liked this fic, & are craving some more Optimus/Mikaela shenanigans, you can now head over there & read a little more of them. :)

Thanks again for everyone who fav'd/reviewed this story, & hopefully I'll find the time to write/post a new chapter of E-Brakes On before the new movie is out ;D.
