A/N: This story was originally written as part of a 30-Day OTP Challenge. Eight of the little stories I wrote arranged themselves in a sort of "how they got together" thing, while the first and last story could be seen as a "bookend" of the story, explaining how they'd drifted apart over the years and then found each other again. So I pulled out those ten stories, cleaned them up a bit, and I am posting them here.

Chapter 1: Getting Lost Somewhere

Hound slowed, pausing at an intersection, before transforming into root mode. "Huh. I'm all turned around now." He watched as Bluestreak also transformed, and shrugged at the other mech. "I think I took a wrong turn someplace. That's a little embarrassing, considering how long I've been on board."

"That's ok, Hound," Bluestreak said. "It's not like I've seen any of this anyway. It's all new to me, so I don't mind seeing it."

Walking down to an information screen, Hound pressed a few sequences. "Oh yeah, I did take a wrong turn back there. That's why none of this looked right." He pointed down the hallway. "But while we're over here, I might as well show you the oil reservoir."

"Oil reservoir?" Bluestreak fell into step alongside the green mech. "I knew the Lost Light was huge, but it has a whole oil reservoir inside it?"

Hound laughed, and Bluestreak suddenly realized how much he'd missed that sound. "Blue, this ship has entire rooms that none of us have even seen. I wouldn't be surprised if we stumbled on an amusement park at some point." He palmed open a large door. "Here we are."

Bluestreak made an awed noise as they walked into the oil reservoir. The inky blackness of the oil pool reflected the stars visible outside the large windows in the ceiling. "This is... Wow! This is amazing!" Bluestreak looked at the green mech, his optics gleaming in the darkness. "This would be a great place for a party. Or just to hang out."

Hound nodded, looking up at the stars. "Mechs do hang out in here sometimes, but Ultra Magus frowns on non-sanctioned parties in here after Swerve threw one that went a bit out of control." He walked down to the edge of the pool and sat down, patting the deck next to him. "But it's all right to just sit here quietly for a bit. I come in here sometimes to relax and think."

Bluestreak sat next to Hound and leaned back on his hands, looking up at the stars. "This reminds me of that mountain lake we found by accident that once, on Earth," he said. "That was really beautiful. The water was so calm, like the oil is here, and the stars looked almost the same."

"It was pretty, wasn't it?" Hound asked. He laughed softly. "We spent so long there that Prowl ended up sending Bee and Huffer to come find us." He shifted and his fingers brushed against Bluestreak's. "Sorry," he murmured, pulling his hand away.

"It's ok."

They sat in silence for a minute, looking up at the stars together.

Bluestreak turned slightly to look at the green mech. "Hound... What... What happened to us?"

After a pause, Hound shrugged. "I'm not sure. Different assignments. Too much time apart. Life, I guess." He looked back at Bluestreak, his field tinged with regret. "I think we just grew apart."

"Yeah. I guess makes sense." Bluestreak looked back over the surface of the oil. "I just hate how it seems to have happened without us noticing."

Hound said nothing, and just sat staring out over the reservoir.

Bluestreak kicked his pedes, brushing them against the surface of the oil. He watched the thick ripples for a moment. "Are you seeing anyone now?"

Hound shook his helm. "No." A pause. "You?"

"No." Bluestreak shifted slightly, and his fingers brushed against Hound's again. "Would it be too weird... Do you want to... I wouldn't mind if we..." Blowing out a vent of air, Bluestreak said, "I didn't join the crew because you were here. But if you wanted to try again, I wouldn't mind. Trying. Just to see." He glanced at Hound shyly. "You know, just to see if it was distance that made us grow apart, or if it was just that we didn't belong together anymore."

Hound looked directly at him and smiled. "I wouldn't mind giving it another try. I thought we had a good thing, you and me," he said. He curled his fingers around Bluestreak's. "And if it doesn't work out... This ship is big enough to lose sight of each other again."
