Chapter 1:

Smokescreen is the younger brother of Optimus Prime and Megatron. Yet .... not everyone knows. Separated at a young age, Smokescreen was experimented on, trained to fight .... and kill. Alpha Trion finds out about him and treats him with kindness.
Smokescreen remembers everything. He wants to be with both his brothers, but they are on different sides of the war. He finds himself trapped. Neither Optimus nor Megatron know he's their brother they've lost.
Will Smokescreen tell them? Or will he let them continue to believe he's dead? Or will they find out on their own?
