Sometimes he questioned his own leadership skills. His 'team' had never bothered to tell him anything of what had occurred with past events as well as leaving him out of the loop. All of that had Bumblebee burst out at him in the end rather rudely. It ate at his circuits in annoyance, all he wanted was to be a good leader to his team. He never meant to hurt anyone's feelings or make Sari cry..
Momentarily snapping out from his thoughts, he watched on as the Autobots geared up to face up and off against the Decepticon invasion.

However his vision was suddenly overtaken by a sudden sharp of blue light that had emitted from Sari's key. The bots and the girl let out their own yells of surprise
Not too long after, the group found themselves in a different area than the base. Panicked over what had just happened. Bumblebee was already on his aft on the ground, with a hand rubbing at his head while gritting his dentaes.

"What just happened!? We were just in the base and now we're here!?"

Prowl didn't make much of a comment, silently observing the area around them like usual, he then shifted one weight onto his leg and shifted his arms to fold calmly over his chasis.

"I think we were brought here for a reason. Try at least observe your surroundings first Bumblebee."

Spitefully ignoring him briefly, Bumblebee moved to get up and noticed Ratchet already groaning out. The old medic bot was already letting out a string of Cybertrionian curses under his breath. Turning to face Prowl with a scrunched up look on his faceplates, the bot was already throwing his hands in the air as if to get his point across.

"Reason? Reason!? I think this a trap! We should be getting out of here Prowl! Not standing around here awaiting certain death!" Bumblebee argued out already looking around with his blue optics to see if he could find a way, yet in a nanoklik Ratchet took notice of Optimus moving to sit up with a low groan.

Going over, he kneel-ed some with a hand somewhat brushing his kid being his priority.
"Hold in there kid. It just seems we were taken to some place. Are you hurt? Can you stand up?"

Shaking his head.
"No I'm not. I'm entirely fine Ratchet. Where's Sari?"

"Right here Optimus!" A small high-pitched voice said out, Optimus looked over to the girl already standing there looking over him with her key strongly grasped in her balled up hand her expression written with worry.

"Are you hurt?"

"No! it was just sudden." Sari replied out but then gestured to the area around here which seemed to her to be like a movie-theatre-like room.
With chairs separated on each side with a division bar to keep the sides split up or most likely to keep anyone from attacking each other.

"What a weird theater."

Taking notice of a note neatly folded nearby, Sari approached it to then take it and unfold it and gaze at it with a blink. Finding to be quite interesting.

"Um guys?" She said out aloud.

The bots had stopped their arguing (mostly Bumblebee) and turned their attention onto the girl.

"This note reads:
Dear fellow bots and human.
You were brought here today to witness what true teamwork looks like. Observe another universe of yourselves and learn from them to help your own team-building and learn not to take your team for granted."

Optimus somewhat glanced a little annoyed at the note with a beep, and Bumblebee childishly ignored it. Prowl didn't comment but tightened his expression. Ratchet grumpily was staring at the three bots with a shake of his head.
He wasn't blind to the tension building around the three bots.

Bulkhead was oddly quiet, the big bot preferring to stay out of what the feud was between Optimus and Bee.

"However you won't be watching alone. The Decepticons will be joining you too—"

"WHAT? HAVE YOU LOST YOUR BOLTS?" Bumblebee yelled out with a balled up hand as if it injustice.
"There's no way I'm sharing a room with a Decepticreeps!" He folded his arms with a turn of his head.

Just to then get slapped by Ratchet emitting an 'ooww' noise.
"Quiet kid! No one wants to hear your shouting."

Optimus's spark leap with a nervous feeling about being in a room with them. Especially with Megatron of all bots! It sent uncanny shivers down his spinal strut. Internally he started to do an internal weapons scan to see if his weapons were still online.. much to his disappointment they were truthfully disabled. Yet it didn't stop the bot from using physical force if needed to.

"Your weapons systems have been temporarily been disabled for the time being, the same will go for the Decepticons when they get here. Your two groups will split on each side of the room to start and get it over with. Good luck watching and no fighting."

Staring at the note Sari couldn't help but crumple it up and throw it to the side with a 'hmph' radiating off of her.

Not too long after, the Decepticons appeared on the other side, consisting of:
Megatron, Starscream, Lugnut, Blitzwing, Shockwave and Blackarachnia.

Seeming confused, the bots freaked out the sight of the Autobots and prepared to fight yet most of them realized they could not use their weapons or transform.

"What is the meaning of this-"
"I'm going to blow up-"
"wooohoo so funn! What is this place Megatron!?" Blitzwing cackled out, making Bumblebee flinch out some to the mech's deranged personalities.

Starscream wasn't doing any better, he had to be next to Lugnut who was already loudly praising Megatron.

"Shut up you giant oaf!" He screeched, moving to shove Lugnut away.
"We should be eliminating Autobots! Right 'master'?!" He glanced at Megatron expectantly.

The bigger bot didn't reply.
In fact, he stayed quiet and wasn't freaking out like the rest of them. Observing of Optimus with a narrowed eyed look. Seeming to understand their situation.

Blackarachnia could only 'tsk' at the cons behavior. She swore every single time it was like this. At least blue tailfish head over there knew when to be quiet.

"We're not here fight. We've been teleported here to watch something." Optimus started out.

"Liar!" Starscream screeched pointing at the Autobot.

"Starscream." Megatron warned out with a calm voice.
"I suggest you listen. Our weapons are disabled. Perhaps this may be entertaining, at least we do not have to share a side with the Autobots"

His eyes never left Optimus. Which had the bot glaring at him defiantly. Despite his humiliating 50 stellar-cycle imprisonment, there was something about the red-blue mech that intrigued him.

Still triggered Starscream didn't bother making much of a fuss, instead stomped over to their side of the theater room to then sit in a seat with his arms crossed. The poor seat already crushing under his metallic weight mumbling promises under his breath.
The other Decepitcons didn't dare to argue against their leader, following Starscream's example by sitting in their own seats. Sadly crushing under their weight. Blackarachnia preferred to stand in the corner of the room with her arms folded over her chasis.

The Autobots hadn't made a noise, in fact most reluctantly taking a seat in which the chairs fell under their weight as well.
Sari decided to sit in-between Optimus and Ratchet feeling most safer there with them. Bumblebee sat furthest from Optimus on Ratchet's other side as Bulkhead taken a seat in the back with Prowl standing in the other corner silently watching what's going to happen next, sides he didn't feel exactly comfortable with a Con' standing in the other corner so why shouldn't he for his corner?

"Do we really have to share a room with them?" Sari whispered out some with a slanted look to Ratchet.

"Unfortunately we aren't left with any choice. So let's get this over with. I'd rather be anywhere but here."

Notes:

This is only the beginning. My hyperfixation has a tight hold on my brain ;3;
So I haven't seen any fic include Shockwave in reaction fics so there he is. The devils father /j

Can't promise regular updates as my posts tend to be irregular.

But for now, all I can do is find the script of the episodes and start typing out from there.
