So Bumblebee does have a talking line in DOTM?

I didn't notice it when I watched the movie but I was just checking out some clips on youtube and when Soundwave kills Que Bumblee says "goodbye my old friend". Is that correct or am i just hearing things?

He was speaking with the radio,not a line

Does Bumblebee have any real line in the movie?

He had two in movie 1,and 0 in the others

I swear to God, "Goodbye My Old friend." is in Mark Ryan's voice, I could recognize it anywhere.

Many people have to said to me that it isn't, BUT JESUS CHRIST just listen to him speaking! THAT'S GODDAMN MARK RYAN!

It is not in his voice,it is radio speak

It's not. Mark Ryan has an accent. And also sounds completely different than the voice he used in that scene.

Also when BB actually talks (like at the end of the first movie and in that deleted trailer bit where he says Sam's name after a radio sentence) his mouth plate/detail bobs up and down Optimus-style. It didn't there.

Unfortunately, you can't prove it [neither can I for that matter].

But seriously, take another look at the audio and tell me it doesn't sound a hell lot like Mark Ryan.

EDIT: Post refering to Seekerblackout.

Was it ever explained why he reverted back to silent Bee after the first movie?

if you consider the comics canon, Starscream shot bee on his vocal prossecors when screamer was fighting fellow decepticon wreckage
