There's a lot of TFA art coming hahahahha
When Cyclonus fell out of the skies over New Kaon, he did not fall alone; Cyclotron came through with him.
He did not need as much reassembling as Cyclonus did and as soon as Scalpel had Cyclonus online Cyclotron naturally homed in on his signal.
Thankfully Scalpel was fine with keeping the youngster a secret as he did not ultimately care, but other Decepticons would and with nowhere else to go and no idea how to return “home” Cyclonus swore loyalty to Megatron and became a member of Team Chaar.
Cyclotron however was to remain hidden, the less people knew and the less he was exposed to the war the better. Cyclonus took on a nihilistic attitude as a defense against potential interlopers discovering Cyclotron.
Cyclotron did his best to stay hidden and live happily but a curious youngster is, well, curious and Cyclonus always had to keep an optic on him.
Cyclotron also knows Cyclonus is very upset and sad so he does his best to cheer him up.
They’re both alone and upset, they miss their home, they miss their family.
