This scene was set after Starscream had manage to capture the sparkling teammates from Bee. Somehow he find out about them and is using them to get the Allspark fragments the bots have:

Starscream place the screaming sparklings down before leaving them alone. Optimus and Bulkhead try to break free from the energy grid but it was too strong.
"It's no use." chriped Prowl. "It's too strong."
Optimus stopped then look at him. "Well, we got to do something. Bumblebee can't handle Starscream by himself."
"Well neither can us." chriped Ratchet. "Not in this condition."
Bulkhead signed and slide down. "I hope he's okay." he beeped sadly. He miss feeling the yellow mech's warm spark.
Optimus sat down next to him as well as the others. "Me too."

When Bee came back online the first thing he do was look around for his sparklings. When he remember what happen, anger boiled up inside of him. Starscream was going to pay dearly for taking his sparklings.
He got up, ingoring any pain he might be feeling. He had no idea where Starscream was hidding but he knew two things; find the sparkling as soon as possible and follow the direction his spark was leading him. He transform and speed down the road determine to get the little ones back no matter what the cost.

Starscream was in a good mood. He was just a few hours away from up taning the all-spark fragments the Autobots had. This orginal plan was to capture the yellow mini-bot and have the other Autobots deliver the fragments to him in exchange. But seeing as the others have been turn into sparklings and the yellow bot doesn't pose a threat to him he figured he'll have the mini-bot deliver the fragment instead.
He took a glimpse of the room he place the sparklings to see that they have cuddle up against each other for a recharge. He smiled. Maybe he could reprogram them into decepticons. He could use some loyal minions, something better than those clones. after all a sparkling's firewall are very young and not very strong against reprogramming files. Yes, maybe he will do that.

"Okay, let me get this straight." said Lockdown. "You want to use my ship to hitch a ride to the moon so you can take out Starscream and rescue four little sparklings."
Bumblebee just look at him with determintion. He didn't know how he found Lockdown, most of his memories was kind of a blur but he knew he just have to get up there. That's were his spark was leading him. He nodded, "Yes. And I promise to pay you back."
"That's nice and everythng, sunshine, but what makes you think I'll give it to you?" Lockdown said with a smirk.
Before he can blink, Bumblebee grab his neck and pulled him into eye-level. "Because if you don't, I'll just stuff those upgrades of yours up your aft if you keep me from reaching them any longer." Bee threaten in a low, dark voice.
Lockdown knew he was serious. The fact that his grib was a little tight and he was actually a little scare of him right now kind of prove it. "Okay, okay, you can borrow my ship." he said. "But you'll owe me."
"I plan on it." reply Bee.
Lockdown lead him to a small ship he could use to get to the moon. Bumblebee thank him, started the ship, and headed towards the moon. Lockdown watch as the ship flew up into space. He shock his head, "That mech will make a great creator."
