Uh, yes. In the first one win sector seven is attacking bumblebee with there special wepons you can feel Sam's emotion. Also in the third one when the Decepicons are about to "kill" Bumblebee. Speaking of sector seven's wepons why didn't they keep those around?
I've decided I need to rewatch The Iron Giant.
Also I have to put Sam snd Bumblebee out there as a relationship that is just as strong as the others mentioned.
