It´s my opinion that Silas and MECH´s purpose in the show are not mere being third class antagonist, but to show human´s potential (even for evil deeds). Let´s review the facts: -Silas was only half-surprised when he discovered about the bots (he probably has some secret contacts with the army or the government). -After their first enconter, they managed to lure both Bulkhead and Breakdown with a bait signal, capture Breakdown (an experienced and powerful warrior), dissect him (it´s implied they had figured a lot about cybertronian anatomy, to the point of dissactivate BD´s neural sensor of pain) while keeping at bay to the autobots (the scene with BD´s stolen eye was probably the best part of the chapter) -In the Crisscross episode, they effectively blocked all transmissions (including Arcee´s, with are supposed far more avanced than human tech´s equivalent) except theirs. And they learn about cybertronian´s transformation secret only watching Airachnid scan Fowler´s helicopter). -In Operation Bumblebee, they have learned about the Cog, and they manages to remove BB´s one in situ and leave even before Bulkhead show up. Also, they have a proto-transformer almost functional and able to transform (or so would be if they knew about the "Only Energon" detail). My only complain is, in fact, they learn and progress too fast in their knowledge of alien technology to be credible.
