you had accidentally discovered the hideout of the decepticons which went badly since they came after you and attacked you but thankfully you were saved by Optimus but it resulted in a very very long lecture with him though who can blame him? You found something you didn't mean to find and you were attacked for it nearly dying in the process had he not came after you and brought you back to the autobots base to recover though he was upset with you, he seemed more worried about you given everything you both went through together as friends and comrades. Recently you noticed your autospark seemed off but you didn't think much of it till Optimus went on a mission with Bumblebee and Arcee leaving you at base but at least your not alone here but after six months did it get worse so you went to Ratchet to find out why and in doing so did you find out you were carrying small sparkling within that were clearly Optimus' which shocked and surprised you but it seems that Optimus is finally back after a month since your about seven months in now but you'll need to tell him right when he gets inside the base as their ship landed outside though the other autobots on base knew since Ratchet accidentally yelled out loud about it since he was surprised the first time but at least he apologized afterwards but now you'll have to explain everything to Optimus once he's inside the base...
