A month have pasted since Strongarm last visited Bumblebee, she didn't tell anyone about his condition and she's been praying to Primus that he would get better.

Optimus have received that news that Bumblebee have kept himself away from his team without reason and he decided to visit his son, which no one knows about their relationship.

Optimus greeted the Bee Team and he then advanced towards Bumblebee's room, finding his son sitting on his bed leaning against the wall that was next to it and listening to something, blindfolded.

"Bumblebee." Optimus said, his voice so stern that it made Bumblebee drop his phone and pull his earphones out. "Optimus!" He yelled and looked around for the Prime, who stood by the door.

Optimus walked in and stood in front of the yellow mech and ordered, "Remove the blindfold, I need to see my son."

Bumblebee looked up at Optimus, then down. He hesitatingly removes the blindfold and revealed his no longer blue eyes, instead, the were grey. The colour of death itself.

"There, are you satisfied?" Bumblebee asked, dropping his gaze onto Optimus, even though he cannot see. "No. I'm sorry." Optimus replied, eyes dropping their deadly glare and turning into eyes with care and sorriness.

"You are?" Bee asked, raising his eyes up with hope and wonder. "Yes. I'm sorry I wasn't here." Optimus replies, honestly filed in his voice. The most caring voice that Bumblebee has ever heard.

Optimus wrapped his arms around his blinded son, fixing their long broken bond. One that was broken since Optimus left to restore Cybertron by joining with the core.

Bumblebee placed his head in Optimus' should as he cried into it, his Energon leaving his eyes as happiness and not injury.

Optimus soon let Bumblebee go. As the younger mech caught his breath, Optimus picked up how phone and looked at what Bumblebee was listening to.

"Moonwatcher's lullaby?" Optimus asked, holding Bumblebee's phone and looking at the song information. "Yes. The song you used to play me every time I was in the hospital and was scared. All those times before the war. I just miss it, and I've never got the chance to ask you to play it for me again." Bumblebee replies.

Optimus smiles and saw the piano that was in the room. Bumblebee must've had it there just in case he can ask his father to play him the lullaby.

Optimus walked over to the piano and started playing Moonwatcher's lullaby, and soon enough. Bumblebee laid down on his bed and quickly drifted off to sleep. Optimus didn't mind, he finished the lullaby and left his son quietly, letting him rest.
