Blurr's too real nightmare terrifies him but gets (Y/N) to sleep with him.
There's an outbreak of rust. Many Cybertronians have died. Some stay behind to try to treat the infected, while many decide to flee the planet. Blurr got Bumblebee, Hot Rod, and (Y/N) spots on one of the last ships off the planet. He knows there's going to be an argument once he reveals he's staying behind.
The four of them made it to the location. (Y/N) is exhausted, but the three mechs assume it's because of the long travel, and (Y/N) was too stubborn to let one of them carry her.
"Ok, here are the tickets," Blurr says, handing Bee three tickets.
Part of the conversation during the trip was how people still needed to get tickets. Even if official ones are free, making it easy to spot resales.
"Uh, there's four of of us," Bumblebee points out, dreading what Blurr will say.
"I-I'm staying here," Blurr nervously admits.
"What?!" Bumblebee and Hot Rod ask.
"I know Velocitron is your home, but don't be so foolish! You'll only die! I need you, Blurr! I love you!"
The three mechs are surprised. The question is, does she mean it or just saying anything to get Blurr to come with them?
Blurr picks her up and kisses her. (Y/N) kissed back — until she passes out.
The three mechs thought exhaustion got to her, and Blurr would carry her to the ship until they see her lips turn blue.
"Y-you don't think?" Hot Rod asks, refusing to finish his thought.
Even though none of them are medics, they can check basic vitals, and Bee dreads confirming (Y/N) is dying. They watch her stop breathing and find out that though she's not cybertronian, her body still turns to dust.
"No, no, no!" Blurr cries.
Blurr wakes up, screaming as tears roll down his face. The lights turn on, showing he's in his holoform, laying in a bed. He sees (Y/N) standing in the doorway with a frying pan, thinking a Decepticon was attacking.
"And, how would a frying pan help me?" Blurr laughs, but sounds like he's crying.
"What happened?" (Y/N) asks.
Blurr hugs (Y/N) tight and cries while telling her his nightmare about her death. (Y/N) comforts Blurr, promising that she will not leave him or forsake him as long as she lives.
"I love you and will stay with you forever," (Y/N) kisses Blurr as he cries.
Blurr begs (Y/N) to stay and sleep with him.
(Y/N) can tell he's frightened by his nightmare.
"Yes, of course," she says and lays next to him.
