Sorry I can't remember the name of it but does anyone have the EngiPyro friendship fic where Pyro messes up his flamethrower trying to make modifications and Engineer fixes it for him? I believe he makes it into a BackBurner and begins to understand Pyro better since they tend to hang out more in his workshop? I also remember Pyro having complaints that his BLU counterpart's flame was hotter, hence the tinkering with his flamethrower.
