Whose to say the old friend isn't Shockwave?
Here's how it would work, Shockwave is no longer loyal to Megatron (he is loyal to Cybertron only) and knows of Starscream finding cloning tech. So in the past at some point he and Arcee helped each other out and are "allies" in the "I hate you, but I hate (insert name) more" and the Autobots acknowledge that he wants to save Cybertron. So Ol' One Eye comes up with a kill three birds with one stone type plan using his connection to Arcee. Arcee hates Screamer-He wants the clone tech to build himself an army-Autobots hate Megatron so they would jump on board as long as he plays nice. So sic' Arcee on Starscream. Sic' new army (and the Autobots) on the 'Cons. Save Cybertron.
Only he needs a way to get Arcee on board first, and Screamer just happens to have gotten his hands on a now VERY convenient Weapon of Mass Destruction (The Apex Armor) that also happens to be very threatening.
Shockwave, making Batman feel slightly outdated.

Due to his rather unique birth, Grimlock has a slow but endearing speech pattern, which can easily make you forget he's Godzilla with style. And weapons.
