All right, this is yet another new Hey Arnold fic that I had in mind... I wanted to do something with this pairing, but I had no idea how to approach the idea... at least, until just recently! So, for Olga fans, hope you enjoy this one! Anyway, enjoy!

Arnold Shortman was looking up at the door of an apartment building. He looked down at the note as he read it to himself.

'Arnold...

Hope you got this note and kept it to yourself. I still remember you from the good times in society. Listen to me and listen good. I need you to come over to the new Monkey-lair, as addressed below. I need you to be quick!

MONKEYMAN!'

Arnold could imagine the last part of the note with the name on it being Monkeyman's signature shout, but chuckled to himself as he rang the doorbell.

As expected, the door creaked open a bit as Monkeyman peeked out, being cautious. When he saw who it is, he gave a smile, then stared. "What's the password?"

Arnold took a deep breath as he said, "These bananas are a little ripe at this time of day..."

The brown haired man in the white M shirt opened the door up, motioning Arnold inside. As Arnold came in, he looked up at Monkeyman in confusion as he asked, "I came over as soon as I got the note. Is everything okay, Monkeyman?"

"Well... things are going okay... doing fine... well..." Monkeyman sighed. "...you know how I always go out there... Monkeyman... to save the city at night, maybe during the day sometimes to protect the city from harm?"

"Of course, I clearly remember." Arnold smiled. "And you're one of the only, if not best, superhero that Hillwood deserves."

"I'm flattered, fellow citizen... monkeyman!" Monkeyman gave a smile... then sighed. "Unfortunately, as much as my... er..."

"Your aunt and uncle?" Arnold guessed, noticing Monkeyman glancing towards a picture of two smiling people in their lives.

"...yeah. Them. Monkeyman." Monkeyman sighed. "They know what I do for the city and while they appreciate it, they still won't understand just how I'll never fit in to society."

"You managed to fit in." Arnold smiled.

"Yeah, one time. But even then, that one time I did so, I screwed up and didn't save a citizen..." Monkeyman sighed. "Sure, I'm sure I made up for it, but it was still a bit of a blow."

"At least you're over it." Arnold reassured the guy.

"Eh, thanks, but it still hurt my pride." Monkeyman sighed. "But my aunt and uncle... monkeyman... they want me to go out into the real world..."

"What's wrong with that? You've done it before, I'm sure you can do it again..."

"It's not that simple." Monkeyman sighed. "They want me to get a girlfriend."

Arnold blinked in confusion, then his eyes widened. "OH!"

"Yeah. Oh. They love me for who I am and what I do, but it doesn't mean they're impatient..." Monkeyman sighed. "They always tell me, 'You need a girlfriend' or 'Kevin, you have to take a break and settle down with someone!'"

"Kevin?" Arnold raised an eyebrow.

Monkeyman yelped as he sighed, "Er, that's my... secret identity. Listen, citizen, would you mind not spreading that around?"

"Your secret is safe with me, but... KEVIN? Wow!" Arnold said, scratching his head. "I never would have guessed that as your real name... but seriously, I don't know if I can help you with the girl thing... but if you want me to help you be a little more... presentable, I'm sure maybe I can give you a hand..."

"Well... it would really put me up in a good standing... thanks, Arnold." Monkeyman said as he went over to his room. "Could you follow me to my room and help me select some clothes for me to be... you know... presentable, like a regular citizen?"

"Sure, I'd be happy to." Arnold said as he followed Monkeyman inside his room as Arnold got comfortable, sitting down near a chair.

"I'll just be in the closet, digging things out. Just give me a few seconds." Monkeyman said as he went inside the closet, as if digging around for clothes.

It was around this time, Arnold paused as he looked around Monkeyman's room. It was a pretty standard room for the most part, a couple of posters of monkeys present on the wall, but other than that, it seemed to be a pretty ordinary room with a good bed, a stereo, and a desk which Arnold was sitting next to. Arnold then noticed a picture sitting near the mirror. He took a closer look at the picture as he examined the picture. He noticed a person being circled, with an arrow pointing to that person, with the beginning point of the arrow indicating, "Monkeyman!"

Arnold shook his head before looking at all the people in the picture.

"I see you've noticed my high school graduation photo, fellow citizen."

Arnold turned to Monkeyman, who had just came up behind him with a few shirts. "This is your high school graduation photo?"

Monkeyman nodded. "Indeed. Though not much, I still remember the good times back in high school before I became who I am today."

"Were you popular back in your time?" Arnold asked as Monkeyman sat down next to him.

Monkeyman sighed. "I want to say I was... monkeyman... but thanks to the little tic I suffered, they were just well... not really good people to me. The only people who took sympathy was a blonde haired girl, but even then, we hadn't talked all that much."

"Oh..." Arnold said as Monkeyman examined the picture.

"Here she is, this is the girl right there... near the center, bottom row." Monkeyman said, pointing to a smiling girl in the picture.

Arnold managed to examine the girl in the photo as he squinted. "You know, that girl looks eerily familiar... almost like I know who she is..."

Arnold looked closer at the smiling girl with straight blonde hair with a black ribbon present on her head.

"BABY SISTER!" An excitable, straight blonde hair with black ribbon girl smiled as she pulled a blonde haired with two pigtails, pink bow wearing girl towards a hug.

The pink bow wearing girl, known as Helga Pataki, seem to be struggling a bit as she looked ready to punch her big sister, but knew she wouldn't do it. "Olga, if you don't let me go in two seconds..."

The black ribbon wearing girl, known as Olga Pataki, gave a chuckle as she let go of her as Helga rubbed her head as Olga gave a giggle. "Oh, I can't wait for us to spend quality time together! I know I've always said that and we never do so successfully, but this time, this is for real!"

"Oh... joy..." Helga said, groaning. "Look, if you're looking for Mom and Dad, they're not home right now..."

"Oh, I know that, silly!" Olga smiled. "Daddy already called me up and told me that he and Mummy would be running a little late."

Helga sighed as Olga pulled out the letters she got from the mailbox. "Anyway, I got the mail, so after I sort this all out, I'll take you to dinner. Any place you like, I'll pay."

Helga groaned as Olga went into the kitchen to sort through the letters. "Why did she have to come back from Alaska... and spend an entire month HERE, on that note? I know how this is going to end by now... Olga's going to try to somehow humiliate me or make me feel inferior, I just know it! On the other hand, she said she was paying for dinner tonight, so... I guess that's not so bad..."

Helga's thoughts were cut short when a loud squeal of amazement came from the room. Helga yelped, holding her ears as Olga came out. "Geez, Olga, simmer down!"

"I'm sorry, I'm sorry, it's just... my high school reunion is coming up in a couple of days!" Olga said in excitement.

"A high school reunion? This early?" Helga said in surprise.

"Oh, I haven't seen my old friends since you started pre-school..." Olga smiled.

"I bet you were popular with all the other kids, huh?" Helga smirked.

"Well, I was popular, just..." Olga smiled... then started to feel a little down. "...just not exactly with the kids..."

Olga then gave a smile. "But it doesn't matter! I have to make my grand appearance! It's been quite a while..."

"Well... shame I won't be able to come along to your reunion, at least-" Helga started.

"On the contrary, baby sister, this could also be a PERFECT time for bonding!" Olga smiled. "And you know what? I'll be taking you as my plus one! You're going to have so much fun, baby sister!"

"What? Can I have a say in-" Helga started, but Olga didn't seem to hear her.

"Oh, this is going to be just super!" Olga smiled as she ran upstairs.

Helga groaned, holding her head. This was not going to be a good month...

"And you got an invitation to your high school reunion?" Arnold said as Monkeyman was comparing shirts.

"Yeah, but I don't know if I'll go. You know me, citizen... monkeyman... not really fitting in..." Monkeyman sighed.

"Are you kidding me? Monkeyman, this is perfect!" Arnold smiled.

"Perfect?" Monkeyman said in surprise.

"Yeah. Your aunt and uncle want you to socialize, right? Well... this is the perfect time! You have to go to the reunion... catch up with everyone, see how everyone is doing, and tell them about your life!" Arnold smiled.

"...I don't know, Arnold. I can't just approach someone in there and say 'Hello, I'm the kid you people used to make fun, and now I'm a guy who runs around in a blanket, saving the city'. Not really a good line to approach with." Monkeyman sighed.

"You don't HAVE to say you're Monkeyman or even say you run around the streets. Sure, you have a very unorthodox way, but you still save people. Just tell them you save lives. You don't have to say what reputation it is... but just be you. Just don't say you're Monkeyman." Arnold said.

"I don't know..." Monkeyman paused.

"Look, if you're still uncomfortable, I'll be able to help you. I'll tell them about the time you came over and saved me from that gang." Arnold said. "If I word it right, they'll just think you grew up to be part of the police."

"You can do that?" Monkeyman said in surprise.

Arnold smiled. "Sure... but the first thing you need to do... is to say your real name. You can't say you're Monkeyman, even if you have a bad tic of saying 'Monkeyman'."

Monkeyman took a deep breath as he sighed. "I just hope this works..."

"I know it will..." Arnold said. "Who knows, maybe there's a single girl in there who might take a liking to you..."

"Hmmm..." Monkeyman paused... then smiled. "Okay, I'll do it. But it's going to be tough..."

Arnold gave a little smile, knowing this was going to get interesting...
