"Aw, sweet....!" Rhonda grimaced again, sympathetically, as if she could understand that whole "not liking People touching her!" thing; indeed, she didn't realise even that she was still reeling from her childhood abuse,just then.... "I mean, sorry, sweet - but I don't know your father, in fact -- didn't know, I mean to say....!" She was much more slower and much more deliberate in her speech, as she was running out of breath far faster than the clearly healthy little boy.
And then she grimaced yet again as she realised that she was most likely speaking with a bloody orphan - a war orphan, possibly? She could certainly see that happening to a child in the here and now that she was from - especially when the boy mentioned the name "Black"! "Black, though... I DO know the Black family..... As in Sirius Black, I presume?"
