They only re-met at dinner, where Issy found her 2 other best friends sitting at the long Gryffindor table; Charlie was reading a book while eating spaghetti while George swallowed everything he saw.
"Calm down George, the food isn't going to run away." Issy teased. He gave her a cheeky death glare but continued munching. Just then, a great black owl flew into the hall, carrying a letter, and dropped it in front of the girls.
"Isabella Alexis River and Charlotte Scarlett Di Angelo..." Issy read.
"Who's it from?" Fred asked.
"I don't know, it doesn't say" Issy answered, turning the letter around in her hands.
"Open it then!" Charlie rushed. When Issy carefully opened the letter, her eyes widened.
"Charlie! It's from Oscar!" she exclaimed.
"What?!" gasped a shocked Charlotte.
"It says,
Dear Issy and Charlie,
I am terribly sorry that I couldn't reply to any of your previous letters, and that I am writing to you so late, so please forgive me. However, I have just been told that I will be forced to move schools for unknown reasons, and I will be joining Hogwarts School of Witchcraft and Wizardry very shortly. My arrival is expected to be on the coming Tuesday. I hope that you introduce me to your new friends and stay safe. If everything goes right, I shall see both of you on Tuesday.
Lots of love, Oscar Russell Howard"
"'stay safe'? Who does he think he is? My mum?" Charlie protested.
"Who is he?" Fred asked suspiciously, eyeing Issy.
"He's an old friend. All 3 of us used to be inseparable, but then he had to move away because of something. We sent him lots of letters but he never wrote back. I thought he was dead. I can't believe he's coming to Hogwarts. In 2 days as well. I think our Ozzie matured when he was away." Issy explained.
