(A/N: That last chapter turned this story into a DudleyXKitty and BruceXKatrina story! Yay! A double-pairing! Whoo! Now I promised that the story would get better in this chapter, and I'll get started right away so you can find out how.)

It was the month of February in Petropolis. At T.U.F.F. headquarters, everyone knew that February meant Valentine's Day, which was the most romantic day of the year. Still, they weren't concerned about it, because not many of the T.U.F.F. agents had a special somebody.

However, Dudley, Bruce (he got the job at T.U.F.F. on January 2nd), Kitty, and Katrina were the only ones who found love. Dudley and Kitty were in love with each other, and so were Bruce and Katrina! Dudley and Kitty confessed their love before Christmas, but Bruce and Katrina met and fell in love on New Year's Eve (Peg also approved of Bruce and Katrina's relationship). Now Valentine's Day was approaching, and this was the first time they were concerned about it.

When Dudley and Bruce realized that February meant Valentine's Day, they were worried. They never worried about Valentine's Day before, but that's because they never had girlfriends before (okay, Dudley did, but he loves Kitty more than he did 'Fifi', Becky, and Daisy). Now they had girlfriends, and they didn't know what girls would like for Valentine's Day.

"What am I gonna get Kitty? I'm planning on taking her out for dinner, but I wanna give her something first thing in the morning on Valentine's Day." Dudley said.

"I don't know how to help you figure out what to get Kitty, because I don't know what I'm gonna get Katrina." Bruce replied. The brothers thought for a moment, and then Dudley said, "I know! Let's ask Keswick! He's a genius, and he has a girlfriend!" (A/N: In this story, Keswick is still with Tammy.)

"Okay! To the lab!" Bruce said. So they went to the lab to see Keswick, who was busily working on an invention.

"Keswick, Valentine's Day is coming up, and Bruce and I don't know what to get our girlfriends. Do you know what girls would love for Valentine's Day?" Dudley asked.

"You must have some idea of what girls would love for Valentine's Day!" Bruce said.

"I remember s-s-something Kitty suggested to me back when I was tr-tr-trying to win Tammy over. She suggested I give Tammy flowers. Girls l-l-love flowers, so try that." Keswick suggested.

"Good idea! Thanks!" Dudley said.

"That'll work! Thanks, Keswick!" Bruce said.

Then Dudley and Bruce left the lab.

Later that night, when Dudley and Bruce were relaxing at home after a long day of work, Dudley thought back to when he and Kitty first met. Okay, so their first meeting wasn't the best of first meetings, and they didn't like each other right away. But as time went by, they grew to be close friends, and they always came through for each other.

Now they'd been together for a while, and they were hopelessly in love, and Dudley realized that he wanted to marry her.

Bruce noticed the look on Dudley's face, and he wondered what Dudley was thinking about.

"What are you thinking about?" Bruce asked Dudley.

"I'm thinking about asking Kitty to marry me. I love her more than I've ever loved anyone." Dudley said.

"Yeah, I feel the same way about Katrina. But I'm gonna wait a little while longer before proposing." Bruce said.

"Anyway, I'm a little nervous about asking Kitty to marry me. What if she says no?" Dudley asked. sounding worried.

"I've seen how much you two love each other, so I'm sure Kitty will accept your proposal." Bruce said.

"Okay, I'll do it. But first, I have to buy a ring. I'll be back soon." Dudley said.

"You're going to buy it now?" Bruce asked.

"I wanna get it taken care of right away." Dudley said as he left the house.

Several minutes later...

Dudley returned home, carrying a small, black velvet box. Bruce saw the box, and he said, "So you found a ring?"

"Yup! Check it out!" said Dudley, and he opened the box, showing Bruce the ring inside. The ring was a sterling silver band, set with a heart-shaped emerald.

"Dudley, when she sees that ring, she'll definitely accept your proposal!" Bruce said.

"I hope..." Dudley said, for he was still worried that Kitty would say no.

Then Valentine's Day arrived. Dudley and Bruce were on their way to work, but they forgot the flowers, so they went to the flower shop, and while Dudley bought a bouquet of red roses for Kitty, Bruce purchased a bouquet of red, pink, and white roses for Katrina. Then the brothers hurried to T.U.F.F. to see their girlfriends.

When they got to T.U.F.F., the first thing they did was look for Kitty and Katrina. Both Katswells were at their cubicle, working on the computer. So Dudley and Bruce hid the flowers behind their backs before walking over to the girls. When they were close enough, Dudley tapped Kitty's shoulder to get her attention, and she spun around to see him and Bruce.

"Dudley! Bruce!" Kitty exclaimed, happy to see them, but she was happier to see Dudley.

"Brucie's here?!" Katrina asked. She turned around, and upon seeing Bruce, Katrina happily said, "Hi, Brucie!"

"Happy Valentine's Day, Kitty!" Dudley said, handing Kitty the bouquet of roses he got for her.

"Happy Valentine's Day, Katrina baby!" Bruce said as he handed Katrina the bouquet he bought for her.

"For me?! Dudley, you're so sweet! Thank you!" Kitty said, before giving Dudley a kiss on the cheek.

"Oh, Brucie, thank you!" Katrina exclaimed as she grabbed Bruce and kissed him on the lips.

"You're welcome." Dudley and Bruce said in unison, happy that the girls loved the flowers.

"I got something for you, Dudley." Kitty said, and she handed him a heart-shaped box of candy.

"All right! Thanks, Kitty!" Dudley said.

"I have something for you, too, Brucie." Katrina said. She handed him a bag of conversation hearts.

"Thanks, Katrina baby! How about we share these sweets during our break?" Bruce suggested.

"Sounds like a plan." the Katswell twins replied.

Today, the bad guys weren't up to anything, mainly because they didn't have a special somebody (except for Dr. Rabies and Madame Catastrophe, who have each other). And since the bad guys weren't causing mayhem, the Chief allowed the agents to have a Valentine's Day party in the snack room. So all the T.U.F.F. agents (except the Chief, who was in his office) were in the snack room.

Right now, Dudley, Kitty, Bruce, and Katrina were sharing the sweets, and while Bruce and Katrina lovingly gazed at each other, Dudley and Kitty were reminiscing past missions. While they were talking, Dudley was trying to build up the courage to pop the question to Kitty, and he decided that now was the time.

"Kitty, you know that I love you, right?" Dudley began.

"Of course." said Kitty, smiling sweetly.

"You also know that I would do anything to ensure your happiness, right?" Dudley asked as he got down on one knee and reached into his coat pocket (where the ring box was).

"Dudley, what are you getting at?" Kitty asked.

"Will you-?" Dudley asked, before completely freezing in mid-sentence.

"Dudley?" Kitty asked, wondering what had happened to him.

"Baby bro?" said Bruce, also wondering what happened to Dudley.

"Keswick, can you fix Dudley?" Katrina asked the genius as he passed by. Keswick pulled a bucket of cold water from seemingly nowhere and threw it at Dudley. The shock of the water pulled Dudley out of his frozen state (more or less).

"AAAAHHHH! KITTY KATSWELL, WILL YOU MARRY ME?!" Dudley shouted, pulling the ring box out of his pocket and opening it, showing Kitty the ring inside. Kitty let out a gasp of surprise. She certainly wasn't expecting this!

While everyone waited for Kitty to respond, Keswick made a mad dash to the Chief's office.

"CHIEF! CHIEF!" Keswick yelled as he started banging on the door to the Chief's office.

"Come in!" the Chief said.

Keswick burst into the room, trying to catch his breath as he said, "Sorry... to bother... you, Chief... But you'll n-n-never... guess... what just... happened."

"Don't tell me. Let me guess. You asked Tammy to marry you, and she said yes!" the Chief guessed, not looking up from the tiny romance novel he was reading.

"I wish! Still, you were c-c-close! Try again!" Keswick said. The Chief couldn't think of what had happened, so he said, "I give up."

"Dudley asked Kitty to m-m-marry him!" Keswick exclaimed.

"HE WHAT?! Did Kitty accept his proposal?!" the Chief asked, throwing the novel up in the air out of surprise.

"I don't know. After Dudley p-p-popped the question, I came here to tell you!" Keswick said.

"Well, let's find out." the Chief said, catching the novel and putting it away. Keswick picked up the flea, and they went to the snack room to see if Kitty had accepted Dudley's proposal.

When they got there, Dudley was sweating bullets, Kitty still looked surprised, and everyone else wondered if Kitty would ever accept Dudley's proposal.

About a minute later, Kitty did something. She pulled Dudley towards her and kissed him on the lips.

"I'm not sure, but I think that's Kitty's way of accepting Dudley's proposal." the Chief said.

When Kitty broke off the kiss, Dudley needed a 'yes' or 'no' answer, so he decided to ask Kitty the question again.

"Will you marry me, Kitty?" Dudley asked, hoping for the best.

"Yes, Dudley! I will marry you! I love you so much!" Kitty exclaimed as she hugged Dudley, tears of happiness streaming down her cheeks. Everyone began to cheer now, for Kitty accepted Dudley's proposal, and they would get married. When she calmed down a little, she let go of Dudley, who couldn't have been happier as he slipped the ring on her finger.

"I told you she'd accept." Bruce whispered to Dudley.

"I know." Dudley replied, feeling like the luckiest dog alive as he held Kitty close to him. Then everyone got back to partying, but this time, they were celebrating Dudley and Kitty's engagement. Now this was a day the purr-fect partners would never forget, and it made Valentine's Day more special, too.

YAAAAAAAY! Dudley and Kitty are engaged! This is great! Stay tuned for more fun and romance!
