Side Swipe in Only Human?
There is a shot of Kup, Grimlock and what I think is supposed to be perceptor.
I say that because Perceptor is seen running around later. But the first shot when they wave to the coming autobots it sure looks like Sideswipe first.
Its a shame I think this epsiode would have been a good time to bring back some of the G1 season 1 Characters even if they just threw in sidesipe, Sunstriker and hound just standing around.
THe epsiode felt like a season 1, early season 2 episode with the lighter tone and old music score.
Not to mention it took place on earth.
