A/N: I'm going to make this clear. I don't own the Harry Potter series or it's characters. That right goes to JK Rowling

If you haven't yet, read before this story:

Marge Blows Up & the Knightly Bus

It was tea time when Marge first talk to Harry, and that was only after Ripper growled at him.

"So!" she barked. "Your father manage to keep custody of you after all."

"Yes, ma'am." Harry said.

The last time they were in the same house, Marge kept talking about how James will lose custody if he doesn't get his life straight and start working.

"Probably only after getting that job at the university," Marge said. "I really don't see why you still let these two visit, Petunia. If it was up to me, I would kick them to the curve the moment they take first step at the porch."

That basically what it been like for the next three days. Marge sizing up James and Harry.

Pure torture.

Harry tried to keep his distance with Marge, which never was easy as Marge kept wanting to keep an eye on him and comparing him to Dudley.

It was much to their relief when the final day of James and Harry's visit came around. But of course Marge ruined that too. Normally they leave first thing in the morning. However, Marge insisted that the two stay at least until dinner before leaving.

"I'm surprise how much you straighten yourself out, Potter," Marge admitted after having James explain about what exactly he teach. "It's a shame your wife never got the chance to. Then maybe she can redeem herself as a proper woman."

Suddenly the wine glass in Marge's hand broke. The reason wasn't James but rather Harry. After hearing Marge tried to size Harry's dad up, Harry was near the line of breaking, and switching stories to how bad his mum was… well that was the breaking point.

"Oh, look at the time," James said. "Harry and I must really go."

"It be a miracle your son doesn't turn out as dead weight and dead like his mother," Marge continued, ignoring James as Petunia cleaned up. "It's like with the dogs. No matter how much one parent change the child could end up like the other."

"My mum was not no good!" Harry yelled.

"MORE BRANDY!" yelled Vernon, who had gone very white at this point. He emptied a bottle into his sister's new glass. "You two," he snarled at Harry and James. "Don't you two have somewhere else to be."

"Yeah, we do," James said.

"Hold on one second," Marge hiccupped looking at Harry swelling with enjoyment with his outburst. "Go on, boy, go on. Prove to me your mother wasn't no-good."

"That's enough Marge," James snapped. "Let's go Harry!"

"Seems like nothing has change," Marge said. "Same ol' Potters. Trying to be the boss of—"

Marge stopped as words seemed to fail her, and for a good reason. Marge had started swelling up like a balloon. Her great red face started to expand, her tiny eyes bulged, her mouth stretched too tightly for speech—next, several buttons had just burst from her tweed jacket and pinged off the walls. Then she started to rise off her chair and into the ceiling.

"Marge! No!" Vernon yelled as he seized.

"Harry, get our stuff," James said.

Harry nodded and tore through the living room up the stairs. Harry came down with both trunks and owl cage. And just in time too as James deflated Marge and had manage to readjust Marge's memory with the memory charm so she wouldn't remember to night.

"Good night, Vernon and Petunia. See you next year," James said as he helped Harry get their stuff out of the house."

"I'm sorry dad," Harry cried once they were far enough that private drive was no longer in site.

"It's okay, Harry." James said. "Fortunately it was accidental magic, so they won't expel you for using magic out of school, but you might get a warning."

Harry nodded.

"Now, come on. How about we take the knight bus home," James said.

"Okay," Harry agreed.

…

The knightly bus looked like your basic tripple decker violently purple bus that acted as a transportation for Wizards and witches who needs a non-magical form of transportation.

Harry and James waited at the bus stop and not too long later one stopped in front of them. A conductor in a purple uniform leapt out of the bus and began to speak loudly.

"Welcome to the Knight bus, emergency transport for witches and wizards that are stranded. Just stick out your wand hand, step on board, and we can take you anywhere you want to go. My name is Stan Shunpike, and I will be your conductor evening."

"Hello Stan," James said. "My son and I need a ride to Godric Hollow please."

"Very well then," Stan said.

…

The trip wasn't any more pleasant than Marge's Visit. The bus seem to literally flew through the streets, dodging muggles every which way, and the Driver name Ernie Prang. There were a few stops before they made it to Godric Hollow where James told them where to stop.

Once there, James paid Stan and they left the bus.

As expected, there was a letter from the Ministry already there for Harry.

James picked it up and read:

Dear Mr. Potter,

We have received intelligence that you have perform a swelling curse at your Aunt and uncle's place this evening on a Muggle.

As you know, underage wizards are not permitted to perform spells outside the school, and further spellwork on your part may lead to expulsion from said school (Decree for the Reasonable Restriction of Underage Sorcery, 1875, Paragraph C).

We would also ask you to remember that any magical activity that risks notice by members of the non-magical community (Muggles) is a serious offense under section 13 of the International Confederation of Warlocks' Statue of Secrecy.

Enjoy your holidays!"

Yours Sincerely,
Mafalda Hopkirk
Improper use of Magic office
Ministry of magic

"See Harry, no fret," James said.

"Dad, this means the next time I loose control, I can be expelled." Harry said.

"Relax, Harry," James said. "Come on. I'll make us up a cup of hot chocolate before I floo-call Sirius to let him know Hedwig can come home."

That cheered Harry up. He may of lost his chance for Chudley Cannon Quidditch Robes, but at least this evening wasn't a total lost.
