Aegon's just happy to have SOMEONE to continue the Targaryen line right now, because everyone else is either dead or in the case of his sister, refusing to marry or come home. He has generally positive traits as well like kind and none like ruthless, so he wouldn't really be too put out. Plus they can marry siblings because Targs, so if he has a son then a daughter ready to go is pretty good anyway
