One of the mysteries of Hogwarts he was interested in was that of the runes on the giant pendulum in the clock tower, which was what brought the Ravenclaw's feet heading towards the giant clock coming from the courtyard. He had a sketchbook under one arm and a couple of pencils in the other hand. He figured he would take a stab at drawing the runes he saw there before he headed back inside to study them from the comfort of the Commons.

He had not yet considered the fact he was fully rubbish at drawing. Much better in the art of folding paper, thanks to the direction of his younger sisters.

Reaching his destination, Evan leaned himself again the wall, putting a couple of extra pencils behind his ears and keeping one in his hand while he STARED to capture the look of the runes before transcribing them to his paper.
