Not necessarily romantic, I mean relationship in general. Which ones would you like to see explored more. First that comes to mind is Optimus and Ironhide. It's been suggested that they go way back, but nothing has really been shown about their friendship other than the execution scene at the beginning of ROTF. It would be cool if they ended up in a situation similar to something that happened a long time back that they may not have been able to handle before but they come through this time. Also, Shockwave's relationship with Megatron and maybe some insubordination that may have gone on. That would be really cool if Megatron comes to Shockwave weakened only to be overtaken and Shockwave becomes temporary leader. Another could be Shockwave and Soundwave and a possible rift between them over who Megatron trusts more. What're your ideas about this?
that would be interesting to see i just dont want to see any of the old romantic relationships because i think it would be stupid to see that in the movie and it would just take up pointless screen time. plus we already got shia in a romantic situation in the movie, we dont need another
That would be great! Too bad we won't see it. Seriously, these movies are not, at their core, about the Transformers. That's just how the folks in charge wanted it. These films are about Sam and his being drawn into an alien struggle. It's nice that characters like Prime get a bone thrown their way, but that's all we're getting until a reboot. - Coeloptera
I still want more background between optimus and megatron with flashbacks on cybertron but seems that probably wont happen
I like the idea. Too bad it's not gonna happen, considering how we had little to no characterization for both factions in the first two movies. So I wouldn't hold your breath if I were you.
