The humans have a storybook called 'Through the Looking Glass', about a child who escapes the monotony of her chores by going through a mirror and winding up in a strange but fantastical backward world.

That description is only somewhat applicable to your own situation, but it fits well enough. At least, that's what you think in your addled processor.

After several Quartexes of horrors at the hands of the Decepticons as an Autobot prisoner, you're near your breaking point, and it seems they know it too as you're hauled out of your holding cell and dragged in front of a cracked and twisted-looking mirror.

Your optics flicker slightly, audials struggling to pick up what they're saying, something about a gateway...? Suddenly, you're shoved in and the world seems to shift around you, causing your optics to blackout and the urge to purge your tanks of the Energon inside them to arise.

Worried vocals immediately ring out and you're gently lifted up, processor still spinning and unable to register much.

"What in The Pit?" A voice that sounds eerily similar to Megatron's is heard, only it's laced with genuine worry. "Someone, go get Hook or something!" He orders, but most curious of all though, instead of the crimson red optics all Decepticons normally have, these versions have the same blue eyes as Autobots.

When you finally online again, you're surrounded by more Decepticons that all look far less worried than before.

"Why in Primus' name are you here, Autobot?" A bot that looks and sounds like Starscream, aside from his paint job, spits through gritted denta, as another mech places a large servo on his shoulder, giving a small nod, a silent order to back down. Surprisingly, he listens, optics softening as he glances at the mech, who you recognise as Megatron.

Megatron steps forward, "You bear the Autobot Insignia but your optics are blue, and you just fell through a mirror to us. Explain yourself." His vocals are firm but not unkind, almost as if he can sense your apprehension.
