So, the bio for ROTF ice cream truck mentions something that the twins have to "hold on" when in truck mode. Then I remember back in G1's "Five Faces Of Darkness" the constructicons form Devastator and Scavenger says he doesn't have the energy to hold on and Devastator proceeds to attack minus one limb. So do all combiners have to hold on in combined mode? I always assumed that once the combination was complete they were... locked in? If you have 2-6 different personalities trying to function as one, wouldn't the distraction of trying to hold on kinda screw that up?
