you met Megatron sixteen years ago after finding him in the desolate frozen world where you were accidentally left behind when one of his decepticons tripped you and tried to kill you but failed anyways while walking you heard faint cries and followed them where you found Megatron against a tree holding a newly born boy sparkling which caught you off guard at the time until you decided to help him even if he was gonna blow your head off but didn't once he realized you were trying to help and accepted your help. Now years later you encountered him again for a late night encounter but after a few days did the little sparkling you helped those years ago had grown and only saw you as an enemy due to you being an autobot so he impaled you with his weapon almost killing you which set Megatron off but thankfully you were taken back to the autobots where you were treated while Megatron was busy punching his son's face in for hurting you until Optimus stopped him and pulled him away and to you where he also learned you are currently a few weeks carrying his sparkling which upsetted him more as he took your hand and knelt down by the table you were resting on after Ratchet sealed the wound up as you lay there recovering while the sparkling within you is still growing fine without taking any damage whatsoever
