how bulkhead introduced his son, prince, to miko was just as casually as he had introduced him to wheeljack. of course, it was shortly after he had settled in at home with his baby.
he came back to earth to meet up with miko, miko under the impression they were going to catch up on their lives with each other and go to a thrash metal concert with each other after all that time to rock out!! and bulkhead of course was elated to see miko because of course he was and miko just as ecstatic and she hugged him and immediately started telling him all about things she'd been up to in complete word vomit because she was so excited. bulkhead listened to everything that she had to say and once miko gave him the floor to update her on things and all about himself and cybertron he shared a few things before he told miko that he had a surprise to share with her.
"you own electric guitar?! you got a tattoo?!? GASP-- i know! we'll go on a sand dune escapade like old times!" miko would guess and bounced on her heels.
bulkhead would chuckle at her and shake his head and say "noooot quite. but i do need you to close your eyes for this one because it's a pretty big deal. no peeking either."
miko of course complied and squeezed her eyes shut tight and covered her eyes with her hands to extra hide them, giggling a bit. "i really hope you're not gonna make me eat a leaf like that one time. i still can't get the taste out of my mouth" she'd jest
but something about bulkhead's tone would tell her this was no joke.
miko heard the sound of bulkhead's chest compartment transforming and the sound of some gentle trills and coos. she froze and swore she felt her hair raise at the sound, almost wanting to peek.
to which she did. but was disappointed to find whatever it was was still shielded in the safety of his hands.
"ah ah ah. i said noooo peeking!" and miko huffed at him and was like "aw, c'mon, bulk! you know surprises are hard for me!" she'd throw her hands down dramatically at her sides, exasperated.
and bulkhead could only chuckle, shake his head and roll his eyes. that's his girl.
"alright, alright. you sure you're ready?"
"you know i was born ready, bulkhead!"
"reeeeeally reeeeeally ready?" he'd tease.
"buuulkhead" miko would huff, now impatient.
bulkhead then grinned sharply, lowered his hands to her height as he knelt and opened his hands, revealing the surprise cupped in the palm of his hand as miko tred closer and miko's eyes grew wide. her mouth fell open and at first the only sound she uttered was a breathless squeak.
then she caught her breath and let out the shrillest
"OH MY GOD?!!!!!?? YOU HAD A BABY??!??!"
the entire population of nevada's birds seemed to shoot from the surrounding trees as miko stamped in place and squealed loud in excitement. if she were more self aware at this moment she'd probably remark on that sound being comparable to a metal screech she'd been desperately trying to replicate.
tears welled in bulkhead's eyes, glad that his big news was received well by the one human he valued more than anyone in the world. and he nodded firmly at miko's question. "yep. i sure did. his name is prince. i wished for him at our well of all sparks all by myself"
miko then doted at prince with words of admiration "OH HE'S SO CUTE! HE'S GOT YOUR COLORS AND YOUR JAW AND YOUR WHEELS AND--" she would fall into incomprehensible gibberish and cooing and bulkhead could only find himself nodding along.
prince looked between miko and bulkhead, unsure of how to approach but bulkhead was signalling that miko was a safe person
"prince, this is miko. she's your sister" bulkhead would reassure him further, petting a hand gently on his son's head as he laid the back of his cupped hand against the ground to allow more access between the two.
prince looked from his father to miko and prince reached for her as she reached back in turn, climbing onto bulkhead's hand "he's so beautiful bulkhead, oh my gooooodddd...." miko would sob and gently hug the baby, prince pawing at miko affectionately and rubbing his chin on her. bulkhead would lovingly cradle them both, enjoying this moment.
then the three spent the day catching up with each other, in prince's case getting to know miko, and bulkhead was so happy his family was complete.
