Under the recent change of circumstance, Ianto felt better for returning to the familiarity of the Hub, with the musty rooms and low-lit corridors in which he'd spent countless hours through the last year. Even the dry scent of the cells he caught served its purpose of adding that extra touch of comfort, as did having a point to focus on, something to put his mind to. After what Suzie had informed him about the peculiar pits, he'd soon disappeared down into the archives to pick out relevant research. Pits that brought back the dead and cured the ill. Bottom layer of the files for this one.
After sifting, sorting, cross-referencing and analysing on his initiative, he compiled everything that fell into the realm of slightest relevance, tucked it into a folder, and finally brought it up to the main level. As he unceremoniously walked through the Hub toward Jack's office to check if he'd returned, Ianto saw the light inside, and he knew that his hours of patience had paid off. To that end, he lifted his hand and rapped once on the back of Jack's office door, his knock sharp and perfunctory, before opening it quietly.
Outwardly, Ianto maintained his professional stance, but inwardly his attention focused onto Jack's irritable expression. In the hope to lighten his leader's burden, Ianto offered him a small half-smile that suggested things could still be worse, and held out the folder to him.
