A/N: If a sentence is in italics then that is Bumblebee talking.

(Ratchet's POV)

This was bad. Bumblebee and Arcee have just come back from a energon scouting mission and they were covered in rust. Optimus refuses to get near the both of him due to his immune system pretty much being nonexistent. "Arcee come here." I told her. "Why?" she asked simply. "I wan- need to take a sample of the rust that is covering your armor to see if my theory is correct." I replied. "What is your theory?" "That you and Bumblebee may have cosmic rust." I told her. "There is no way in the pit that we have that." she said. "That is why I said I need to test my theory." I said irritably. "Why is Optimus avoiding me. I just walked by him and he ran and hid in his berth room." beeped Bumblebee. "He probably has the same theory as I do." I told the both of them.

(Arcee's POV)

I cannot believe that Ratchet thinks that me and bee have cosmic rust. That stuff hasn't been seen since all of those mechs on the ARK."Ratchet. Optimus. Were you two on the ARK when all of those mechs caught cosmic rust?" "Yes. That was virus or whatever it was, was horrible to have in your systems." replied Optimus. "I still remember when you helped Preceptor even though you would get infected." said Ratchet. "Which in the end caused most of the crew to catch it." said Optimus sadly. "You were just trying to help." I said. "Yea. I guess." he replied. "Do you regret doing it?" asked Bumblebee. "Not one bit." replied Optimus. "We even made a scientific achievement from the outbreak." said Ratchet. "What was it?" I questioned. "Even though Preceptor was infected with the cosmic rust he created a cure for it called corrostop." said Ratchet. "So this will come off easy with that corro-stuff." I asked. "Yes." replied the medic getting some out of his subspace. "I'm not going to ask why you have that in your subspace." said Optimus. "Rather be safe than sorry." was Ratchet's response.
