Viktor had smiled upon receiving her owl, and told Amiri to set out an extra plate, that Hermione would be joining them. That of course sent the elf off into raptures of muttering and back intot he kitchen to make "something Master Krum's friend would really really like," though of course she tended to mutter in Bulgarian with a smattering of his mother's Roma speech.
What a household, he swore. Half of everyone spoke multiple languages. He wasn't sure that was something he should have encouraged quite as vigorously as he had.
He made sure everything was as reasonably tidy as one could expect with children still up and very awake in the house, and he knew Hermione would forgive the rest. There was just no cleaning up a few things when the children would set up a fuss because they had been going to go back and play with something.
Tsveta was the one who went tearing to the door well ahead of Viktor. He'd told them who was coming, and his daughter was especially delighted. She'd not had a chance to hang out with Hermione in quite a span. She flung open the door -- not too hard, he was relieved to see -- and threw her arms around Hermione's middle. "I've missed you!" she exclaimed happily.
