Megatron and Starscream glared at each other across the cold void of space. The minutes stretched out in to an eternity, with no hope of rescue in sight.
Sometimes, they had staring matches.
Sometimes, they just hurled obscenities at each other.
Sometimes, they just floated in sullen silence.
And sometimes, they had conversations.
"I think it's only fair to tell you..." Starscream told Megatron. "...You're hallucinating me. The real Starscream is still back on Earth. Your CPU has become addled from loneliness and cosmic radiation, and you're imagining that your traitorous subordinate is floating in space just a few mechanometers away, perpetually out of reach."
Megatron's expression was guarded. He didn't reply.
"I mean, it's very convenient that we're both here like this, isn't it?" Starscream added. "You spend every waking moment thinking about killing me, thinking about how easy it would be, and you can't. Sometimes you wonder how long you can remain like this, before your mind cracks entirely. If your underlings do ever find you, what sort of state will you be in? Will you still be fit to lead? Will you still recognise their faces?"
Starscream's words were followed by a long silence. Eventually, Megatron spoke:
"...Starscream," he said. "What do you do if your nose itches?"
Starscream squinted at him. "What?"
"I mean, you have no fingers to scratch it with. Hm. It makes my nose itch, just thinking about it." Megatron weakly lifted his bound hands so that he could scratch at his own face.
Starscream still eyed Megatron like the Decepticon leader had gone insane, but... on cue, Megatron noticed Starscream's nose twitch slightly.
Megatron smiled at him. "I have better things to think about than killing you, you egocentric little hangar queen."
Starscream glared. "A hundred Earth years, Megatron. I give it a hundred Earth years before you snap."
Megatron gave Starscream a withering look. "I wouldn't give you half that."
