=Autobots Base=

It's now about 2 a.m but Optimus are still wide awake. Optimus who's currently sitting inside his office had gotten rather uneasy. His Second in Command has not returned to the base. While its normal for him to leave the base without any notice,he mostly leave for 2 hours,3 hours tops. He should've returned to the base for hours now. 'Something is not right'.His spark can feel it. Optimus has been Bumblebee's guardian ever since he found him on the ruins of Kaon City,he can smell trouble from miles away if its involving his charge. Getting up from his chair,he made his way out of the office and into the Rec. Room. He is surprised to see that he's not the only one awake at the time,in fact,there are quite a lot of bot who's still awake. Ratchet, Bulkhead, Arcee, Smokescreen and some of the new Autobots recruits.

"You are worried about Bumblebee as well?".Ratchet asked while walking towards Optimus.

"Indeed I am old friend".He answered,however as always Prime is able to cover up his emotions so he doesn't sounds worried at all. Being a leader,he must keep his cool and show no emotions at all times,which is something he's very good at."With the rumors about M.E.C.H and Decepticons around,it's hard not to be worried".He continued. Its true,everyone is worried for the same reason.

"We are about to go to your office to ask your permission of sending a search party. I have found his location and it seems like right now he's around the area of the old base of M.E.C.H". Ratchet informed Optimus with a slightly worried tone. While Ratchet is known as a grumpy old medic,he still cares about Bumblebee as much as Optimus does. The fact that he keeps blaming himself the time he cant fix Bumblebee's voice box after Tyger Pax,claiming that "I could have done better" is just one of the times he showed how much he cared about him.

Optimus a little shocked about what Ratchet just told him. M.E.C.H base is nothing but trouble."Alright,the search party will consist of Arcee,Smokescreen,Bulkhead and me. If M.E.C.H are really on operation then we would need to act quickly". Optimus commanded while he take one of the Decepticon Hunter on the special section of the wall. The others also done the same.

At first sight the Decepticon Hunter looks like the hilt of a sword but it actually have a power to shift into any kind of weapon the user prefer to use. The reason it's right now the most favored weapon is that the Decepticon Hunter can switch from ranged weapon to melee weapon vice-versa just by thinking about it. However unlike the other weapons used in the war,the Decepticon Hunter are designed for disabling the enemies rather than killing them which is why some bots calls it "Capture Device".

The team is now ready."Ratchet,open the ground bridge".Optimus commanded. Ratchet gave him a nod as he pull a lever on the ground bridge control. At that instant,a green portal appeared."Autobots,roll out".He commanded the team using his iconic walk through the portal with their weapon ready. If they are going to the M.E.C.H base then theres no such thing such as being too cautious.

=M.E.C.H Base=

Stepping out of the portal they saw the old hangar,on very bad shape. They didn't expected to see that the place looks like it had just recently being burned. The hangar gate are heavily damaged,large holes on the wall and some slice marks. The damage looks fresh with some smoke still coming out of the building. But then it hit them,the smell of human blood,and at large volume.

"What happened here?".Bulkhead said. He's just as shocked as everyone else. The smell of human blood is especially disturbing.

Optimus scanned the building. Just like Bumblebee,he have a sensitive scanner on his optics installed. He found a spark signature belonged to Bumblebee but failed to notice the other one as it was too weak. Bumblebee are able to notice the weak spark signature because of him being a scout. Scouts are trained to spot things faster and more detailed than normal soldiers. He's about to scan for the second time to make sure but got cut off as they heard a voice.

"HELP! ANYONE PLEASE HELP!".Someone inside the building cried for help and the voice sounds like it belongs to a human."PLEASE! PLEASE HAVE MER-".This time,the voice got cut off. Optimus rushed to the hangar,followed by the other Autobots. Its too dark to see anything inside.

After activating his front lights he saw Bumblebee,all scratched up,covered in blood and holding an energon sword which still dripping some blood."B-Bumblebee".Optimus said in shock. He can no longer hide it,his face,his voice,everything about him shows how shocked he is. His optics are focused on Bumblebee.

Bumblebee himself are just as shocked as Optimus are."Optimus".He finally realized what he had been doing. He himself cant believe it,he was so blinded with rage that he forgets everything about being an Autobot. He just keep killing the humans despite their cry for mercy. While on rampage,he for the first time thinks humans as worthless trash thats needed to be discarded and pests that needs to be exterminated. He just froze there. Theres no way out of this. Theres no way to explain about why he done this in the first place. He could've just run away with his sparkling without killing the humans but he didn't.

"Bumblebee,what have you-".Optimus was about to walk over to Bumblebee when he felt something wet on his feet. A red colored substance. Human blood. Losing his focus on Bumblebee,he finally see his surroundings more clearly. At that moment,he could'nt believe his optics anymore. Human corpses everywhere,lying lifeless on the floor. His worried and shocked expression instantly turns into fury."Bumblebee,did you do this?".He asked with a very serious tone. No answer."BUMBLEBEE,ANSWER THE QUESTION!".He commanded now with obvious sign of anger on his voice.

Bumblebee dont know what to do now,theres no way out. He wanted to explain but killing human beings is just as bad as killing a defenseless cybertronian civillian."Yes,I did".He replied,trying to act like he's calm. He knows the consequences of killing humans. However,he's not planning on getting seperated from his sparkling anytime soon.

"Bumblebee,you are now under arrest for-".Optimus is about to capture Bumblebee but got cut off after Bee throw a smoke bomb in the center of the room.

He made way to where he hide his sparkling and blast through the wall. The Autobots starts chasing after him while shooting on his direction. NightStorm, open the ground brige,hurry. He said through the comm. link. He got shot quite a few times because of he's shielding his sparkling.

Optimus also noticed.'Is he trying to protect something?'.He thought. Then he saw what Bumblebee is holding and to his shock,its a sparkling with great resemblance to Bumblebee. Thats when a green portal opened and Bumblebee run through it. They tried to catch up but the it closed befor they even got close.'Why is he protecting a sparkling?And who's sparkling is it?'.Questions builds up on his processor. He opens up the comm. link. Ratchet,open the ground bridge. We are done here.

So? how is it? good,bad or so-so? please review :D
