LOG: Sirius
The rest of the evening went mostly according to plan for Sirius. He'd gotten James to himself and was able to bask in the glow of their lost youth. At least, to him, it felt like he'd been left somewhat behind after Hogwarts. He was in a raucous mood, taking the opportunity to faff about whenever the opportunity arose. A few times he came rather close to blowing the gaff on his issues with Remus, but he'd bitten his tongue and tossed about a few unsavoury jokes instead.
Eventually through their pass on the upper floors of the castle, along with the astute eye of James, he noted some dark magic traces that Dumbledore had spoken of. Sirius felt cold and hatred near the seventh floor, but he wasn't sure how much more they could find at this point, confiding in James his worries that Regulus might know more than he was letting on.
