Megatron had betrayed you
Ever since he left the Decepticons, leaving them to rot and joined the Autobots, you became the one taking care of them. You felt upset, angry, and betrayed all at the same time at Megatron, but you can't really do anything about it.
Starscream had no purpose onto taking Megatron's position anymore, Shockwave didn't know what to do without Megatron's orders, Soundwave stayed as silent as usual, the rest of the Decepticons? They're just hopeless.
but you however, didn't let that happen. Whenever you left, you came back with supplies and energy source, even spare or left over Energon, never empty handed. You took care of them and make sure they're alright, even if you're the only one doing the all work, you didn't care and put everyone else first. They're still your kind after all. Your loyalty to the Decepticons was respected and admired by them.
You may not be a leader, but you can be a caretaker. Providing, feeding, and protecting them, you never stopped taking care of them. This led to the Decepticons to try and please you, whenever they go out and came back, they would give you some valuable things, even if it's small or big.
Ever since the start when Megatron created the faction and you joined, you were just a soldier to them, but now that you proved your worth and loyalty, they could've help but feel grateful about it.
Right now, you were in your quarters, thinking of a plan. Some are in the halls, atleast organizing some things, some are just chilling, some playing, some arguing, etc, etc...
