It seems like she likes him, which means Luke will be watching him closely and very carefully. Even with Clary, he's never been outwardly the overprotective father, understanding that all young women are capable of making their own decisions and to assume otherwise, to assume he knows better because he's older and a man, is an awfully disgusting viewpoint to hold. But he still watches. Just in case the time comes when they do need to ask for help and he can be ready.
