Thinking that once she had enough space for this girl to settle she would simply focus on her business so that was what he did when it came to his. Now, where was he? Something about trolls... Maybe a bit after this line, a bit more. Yes, exactly. That was the place. Therefore there was where Stephen restarted from once he had his own space neatly displayed. For his likes at least, since every time he studied somewhere that place became complete chaos. Books to a corner, piles of parchments all around the table either beneath the books or randomly spread over them, and with a high chance of having ink spilt as well as anything else. Chaos was indeed the best way to describe his method.
However, his thoughts were far away from the truth. More than introducing herself which was only natural considering he had asked for it (not that he was usually answered but someone who would ever be as very respectful as he was by caring to answer them would answer back), this girl, McLanggen for what it seemed, looked like she was starting a conversation even if by asking what was he doing.
First things first though: Stephen grew up in a wizard family. Both his mother and father were wizards even if his mother descended from a Mugleborn. His father, on the other hand, claimed to come from a very long line of wizards which somehow belonged to a branch of a Pureblood family. Stephen didn't know that for sure and honestly, he didn't care as well as his father didn't care for him. Therefore, Stephen could not be any smug Pureblood but he did know who those families were if not by name. And this McLaggen was not so strange to him. He didn't acquire any different posture about the new received information as he was never taught to sort out people by who their families were.
And look where that had gotten him... He would have sighed if he was not already used to the fact that he was a lonely lion among snakes.
"Nice to meet you, Mia McLaggen" he said politely with a smile of his own, one as polite as the words he had spoken. He wasn't quite sure of what she would like to be called by him, a complete invisible stranger, so he decided not to take part on the pick as he hoped she would do so for him if so was her wish.
In the meantime, Stephen had marked the specific line where he was reading with his thumb so he didn't have to look for it again and after a slight glance at his book he then answered: "History of Magic, that dreadful wonderful thing which classes are to die for... What are you studying?"
((Don't worry about it. Take your time if you must and I don't really mind short replies if that is what it gets to be written down.))
