Dora hadn't known,precisely, that Blaise would be here. No. But it was where she would go, probably, and so she'd taken to checking the bar after working late every day since she'd Apparated to his place and read that letter. Blaise was very dear to her, and she hated that things were so hard for him currently. She wished she could help.
So she ordered two drinks, one for him and one for her, at the other end of the bar and walked around to him from the other side. She slipped his onto the bar in front of him with one slim hand and then slipped the arm around him to squeeze him gently.
"Hello, love," she murmured, tilting her head back to peer at him.
