I was thinking about this the other day and was interested to hear yal's thoughts. I'm probably over-analyzing this, but I thought it was an interesting theory none the less. Ya know how in an earlier episode (season 1 finale if I'm not mistaken) during the flashback scene Ratchet called Soundwave Megatron's "first lieutenant?". What makes no sense to me is: when was Soundwave demoted? After they leave for Earth, Starscream is Megatron's first lieutenant, and now Dreadwing. What if Soundwave was like Bumblebee at one point. Had a face, personality and could speak. After realizing Megatronus was abusing his power he attempts to betray him so Megs fucks him up and has Knock Out reformat him into Megatron's personal walking computer (which would mirror Megs fucking Bumblebee up and Ratchet failing to fully fix him). If all this were to be true (not saying it is), maybe when Knock Out is tired of putting up with Megs... reprograms Soundwave back to his normal state? Maybe the synthetic energon Knock Out has could play a role in this? Another thing, Knock Out's comment in the latest episode: "we are fortunate to have him on our side", what exactly did he mean by that? And the fact that he seemed uneasy about having to fix his visor. So yeah, I don't neccasrairly think this is fact, it's just an interesting theory I came up with.
