(Scene: Megatron and Starscream meet on Cybertron as Starscream supervises delivery of the badly-needed energon shipments. Note that neither faces or even acknowledges the other during the course of the song; the lyrics represent the thoughts neither says out loud in Wayward's fic.)
[Music: "All Apologies", (c)1993 Nirvana]

STARSCREAM: Some things just can't be
No apologies
What else can I say?
What a crazy day
Now I understand
Some things can't be planned
All that you can do
Try to lead on through

Sometimes all
You can do is carry on
Megatron
I can't say
I'm sorry, sorry, sorry, sorry

MEGATRON: I never should have risked you
Though you dared me to
So much to regret
Though this mission let
You prove your true worth
You returned to Earth
Loaded with energon
Everything we needed to save Cybertron

Now you're more
Than I thought you'd ever be
But, Starscream
I can't say
I'm sorry, sorry, sorry, sorry
That's just too much

STARSCREAM: Some words are a step too far
MEGATRON: Some words are a step too far
BOTH: Even if today's a start
Some words are a step too far.
