Being Megatron's sparkmate meant being often on his throne with him, showing that you were superior to the others

He acts indifferent or even exhausted when you follow him or talk, but he loves it. It's just to keep his status as lord

Megatron speaks to you in a very soft voice, when you are alone.

Some Decepticons are jealous of your relationship, trying to sabotage your relationship. But you never see those Decepticons again

Megatron tells you how you two will rule Cybertron incredibly well when he destroys the Autobots and how he will start a family with you, his love

You were sitting on the throne, the one next to him

Bored to death, while Knockout was talking

Your sparkmate noticed, and took your hand in his

Megatron:''Is everything okay, sweetspark?''
