Minerva McGonagall was not surprised when Fred II Weasley and James Sirius Potter were both sorted into Gryffindor together. She knew she would have to keep the boys in line much like she did to the twins and the Marauders.
They did everything together, much like the Marauders and Fred and George did during their school days. They often pulled pranks on the Slytherins, but the Slytherin students almost always got revenge in doing pranks back to them. Along with pulling pranks, they laughed, studied, and often had detention together.
But as they say, "Old habits die hard."
