Dantalion looked up as Lena left Thomas' building, pitching his coffee cup as he fell into step behind her. He was careful to keep a decent distance between them, and he'd had rather a lot of experience doing this over the years.
A block away or so from Lena's, he slipped into an alley and shifted into Thomas. He took special care this time to hide the Hellfire in his eyes, and to make sure his head was shaved like Thomas' currently was. He'd even replicated the scar, because if that wasn't there, they'd see through his act in a minute.
He finished the walk to Lena's and pressed the bell, tapping his toes idly on the pavement.
