I recently read OotP again and noticed a bit near the end where Hagrid mentions finding Grawp 'a lady friend'.

Does anyone think he ever managed this? if so, do you think they would have stayed together/ had children etc?
I just find it very interesting because at the end of HBP at Dumbledore's funeral Grawp seems to have been a lot more civillised. I just wonder if his taming would have enabled him to be capable of family life.
