He nodded trial tests would be a necessity. Though one that would take some consideration. As once you burnt your book it was hard to toss into a bonfire later. As he doubted burning just the edges would prove to be enough to test if the book was safe to burn. A even harder factor was the fact that some of his books were used so who knew what was cast on them prior to them becoming his. A detail he had no intention of mentioning or advertising as it was probably assumed if they look a little old they belonged to a cousin, not were purchased in a used book store. Even if it was only a couple of his books that were this way.

Dakota said " At least we have some time to watch if people make mistakes in potions class. As I am sure a lot of people accident burn books then. " Something that made him rather sure second year charms books would be rather safe to be tossed into the fire from his own experience. Even if he had only burnt half the book before the professor stopped it, and gave him a detention. At least he had managed to convince his housemates that a Gryiffindor had been the reason it happened since his partner was one.

Dakota said " My mother played mostly for the Catapults. " Though he was rather sure she played a season somewhere else that he could not remember. He realized that the fact the Catapults had managed to win the European Cup Final in 1956 was a bit to far back in history for Trent to probably remember. After all his mother had probably not even started Hogwarts then. Naturally he was not going to advertise that as the Catapults were not the best team around even if his mother did like them, mostly as they were her team. A loyalty that in Dakota's opinion would only be broken if Wolverhampton got a quidditch team.

Dakota said " Saw it happen once with a seeker being made a chaser. Though the kid ended up playing seeker again about five seasons later. That is the only case I have seen but I am sure there are others, as recruiting while it is for the present also takes into account the future. Also sometimes seeker at Hogwarts is determined only on flying ability not what position a person would be best for. As they say for pick-up games when in doubt make your best flyer seeker." A factor that probably was not true at Hogwarts as graduation put a slight damper on future recruiting. He added " Probably not a Hogwarts concept as teams are based on who is currently in a house with a 4 year average student playing span. " Yes, younger years made the team but in Dakota's observations not enough to count.

off-hand answers are often rather deceiving.
