His Own Frenemy

A/N

Here's the next chapter and thanks for all the reviews so far.

It's amazing that I've gotten so many reviews for something I started the other day huh?

I know Doofy got ill because of Justin but an new reviewer gave me an idea about the platypus flu germs coming from Perry himself making him feel guitly as he made him ill by accident and he wants to nurse him back to health.

Right now I'm listening to Phineas and Ferb songs on my I-Tunes library.

I hope everybody enjoys.

Perry was worried as he paced outside the doctor's office in the O.W.C.A as he was doing tests on Doof but hoped he'd be okay but Justin was feeling bad but needed to tell the turquise furred male that but saw Monogram come out looking grave.

"Agent P come in." he said to him.

He felt swear drop as he entered seeing Doofy sitting on the doctor's table but looked sleepy.

"He somehow got platypus flu germs which his immune system is fighting but it's having a hard time but there's something else I think you should know.

The germs came from you." he said.

Perry's hazel eyes were wide hearing him say that but wasn't buying it but he couldn't believe it.

"I need to take him home." he said.

Monogram nodded in reply as he would let them go home but knew Doof would have some side effects while recovering.

He watched as Perry activated the hover car as he helped Doof get in the car as he started the ignition and took off but was sad as a few stray tears fall from those hazel eyes of his.

He hoped Doof could forgive him.

He saw Doof was asleep and looked so cute and peaceful.

He then landed in the parking lot outside DEI but carried Doof to the apartment by holding onto his collar and using the jetpack and entered through the window but put him gently on the couch but noticed something.

Doof now had a bill like his own.

(Perry's P.O.V)

This isn't good, not at all!

Doofy shouldn't be having a bill for a mouth.

I hope he doesn't have a tail or I'm in deep sludge with Monogram but Doofy needs to know the truth about how he got ill in the first place since I never knew those germs could get into human blood streams but I'm glad Phineas and Ferb are in college as I couldn't risk them getting ill like Doofy.

He's gonna hate me now...

But maybe he'll not be that mad since he thinks it's something from one of his inators even though he heard Francis say he has platypi germs but I need to tell him.

I don't want anything to happen to him.

(End P.O.V)

He then saw Doof sneeze and a chatter came from his mouth.

It scared Perry as Doof chuckled.

"That was strange huh Perry?" he said.

He then blew into a tissue Perry had handed him.

"Thanks but you're such a sweetheart." he said blushing.

Perry felt tears welling up in his eyes.

"There's something I need to tell you.

You thought Justin gave you those platypus flu germs but he didn't.

They came from me.

I swear that I never intended to make you ill but I didn't know those germs could enter human bloodstreams until now.

I'm really sorry.

You hate me now, right?" he said.

"No, No I don't.

I heard you and Francis talking.

But when I realised I had a bill, I had a feeling it wasn't a human virus.

I could never hate you.

We may have been nemeses a long time ago but things changed.

I care about you like you for me." he said.

He then began shivering making Perry nervous knowing the flu was taking it's toll on him but knew a bath would help him as they could use some relaxation plus the steam would open Doof's clogged up nostrils which were bunged up.

He then led him into the bath as he undressed and they both got into the bath as the warm water was soothing but gasped seeing a tail on Doof knowing something wasn't right but he heard Doof laugh as he was washing him with a sponge but Perry couldn't help it but saw that Doof looked a little better but he was nervous hearing him yawn as they got out a hour later but saw him sleeping like he did in pet mode as he took a blood sample and went to get Carl to check it out...
