I thought of a better scene that I think micheal bay should have put in aoe.Instead of cade finding optimus prime cade finds the dead torn body of Jazz from misson city battle cade brings Jazz s body to his farm to study it and the tessa ost score plays as cade studys jazzs dead body
A tie-in comic says Jazz got buried at sea. And would anyone remember Jazz 7 years after he appeared?
You'd think he'd be still remembered. After all he was the first to fall, but your'e right. He did receive a burial at sea though.
Short of Optimus Prime entering the Matrix/Allspark and recruiting fallen comrades Transformers Universe style, or resurrecting him with an Allspark shard like Scalpel did to Megatron.
I think it would be pretty funny if Cade could. It would go a long way to showing just how bad of a doctor Ratchet was. Then you would also have a reason for the Decepticons to kidnap Cade in a later film.
OP I admire you tenacity in wanting Jazz back but that just seems way too farfetched even for these movies.
