Starscream: Lord Megatron, I can explain!
Megatron: Explain what? That you've been hoarding a supply of Energon for your personal use?
Starscream: No! Not exactly... You see I...
Megatron: DO NOT TAKE ME FOR A FOOL, STARSCREAM! I have been wise to your transgressions from the beginning. Not only did you pluck the Dark Energon from my chest, in a failed attempt to snuff my Spark, but you tried to raise your own undead warrior with it. It's no secret that you lost an arm in the process, which you've since had replaced.
Starscream: You know about that?
Megatron: Soundwave is quite competent at surveillance, I can assure you. The fact is Starscream, despite your treachery, I've allowed you to carry on this long because I took a certain delight in following your string of failures. But you've finally become tiresome, predictable... you've hit rock bottom.
Miko Nakadai: We're supposed to be at a rock concert, but all I can see... is rock.
Jack Darby: Relax, Miko. The show doesn't start for two hours.
Miko Nakadai: Do you have any idea how long I've been waiting to see Slash Monkey?
Jack Darby: Uhh...
Miko Nakadai: Forever! And it's their only U.S. date!
Jack Darby: Well, there's a shock. I mean, who doesn't love obscure Bulgarian shriek metal?
Megatron: I suppose helping those less fortunate would be completely out of the question? If that is the case, you may as well use your drill to finish me, I guarantee you will never have a better opportunity than right now... Well, what are you waiting for? Think of the glory! Seize the day! Optimus would.
Jack Darby: No, he wouldn't. Not like this.
Megatron: I will be sure to share the details of our little conversation with Optimus... the day I rip out his Spark!
Starscream: [Having escaped the cave in] Hahahaha! "Predictable", Master? Is that what you called me? Well now who has hit rock bottom?... What's that? I'm sorry, I can't hear you beneath all that rubble! Hahahahaha! Farewell, Lord Megatron! May you rust in peace!
[Starts to walk away but stops]
Starscream: ...But you have survived much worse... If you managed to free yourself, you would blame me for your setback! And there is nowhere that I could possibly escape from your wrath. Or worse yet, your mindless followers would come looking for you, and take credit for your rescue. Credit that could rightfully be mine! RAAAGH! MEGATROOOON!
Bulkhead: If you think I'm going to beg for mercy, Starscream, forget it!
Starscream: Er, yes, begging for mercy would be quite pathetic, wouldn't it? Well, you're much more valuable to me alive. Imagine Megatron's appreciation when I not only rescue him, but deliver an Autobot. I believe that would restore my stature quite nicely.
