Greetings
It was Ron who held back his brothers to let Hermione and Ginny have first crack at hugging Harry, Ron who first held out a hand and then pulled Harry into a firm hug, Ron who greeted Prince T'Challa and then told him, quite seriously, "welcome to wizarding Britain, sir, and with all due respect and gratitude, if you hurt Harry, I— we — will end you."
That earned him a scolding from his mother, who then curtseyed to the prince — and said much the same thing, in slightly more flowery language.
By the time they have been greeted by the whole Weasley family, Hermione, Luna, and Neville, Harry was flushed and flustered and T'Challa was smiling broadly.
"I do believe they care for you, husband," he murmured. "And I am well-warned."
"You're a prince," Harry muttered, although he did not, at least, insist he could look after himself. Not after what had happened. Not to T'challa, who had saved him.
"And so are you," his husband reminded him.
And then it was time to meet the Minister of Magic and the Assistant Minister to Africa.
