Al sidled up to Severus' side. Wasn't it odd that the funerals were the constant events in Al's life which he came to rely on because they put himself and Severus in the same location and in relative peace and quiet for a reliable period of time.
A constant like that was rare, especially in a busy time. And Al'd been busy, adjusting to a new location and getting his mind and body used to working on a new task, but the underlying routine of it was welcome. It wasn't really new, he'd discovered, he'd done it all before at the Prophet. Sticking to a quiet corner and staying away from Busfield's attention - it was Uncle Bill's attention now - and welcoming the quiet monotony of it. Proofreading Peter's new notes and looking up historical references on Hogwarts' defenses and diving into a specific task like a maniac for hours at a time and letting his thoughts fly and outshine the surroundings. Focus. Twelve hours of work a day really weren't enough.
However, this particular disruption to his routine was oddly welcome. Severus would be there, Al thought, even as he left his current notes and reading behind and exited the door before Uncle Bill shooed them out of the new research area and secured the doors behind them.
Al stood by Severus, as he never got a chance to in all the funerals prior, and his mind quietly filled in the numbers: dates of birth, dates of return, dates of death, and years lived in between, mingled with equations of Peter's notes in his mind.
