His daughter was just in a warzone, he's be worried regardless.

As for possible bad blood between Qrow and Taiyang, there's speculation that Ruby might be Qrow's biological daughter and not Taiyanh's. Not much to support that theory, but I wouldn't dismiss it either. Ruby does seem to take after Qrow in fighting stlyes (how well she hands both scythes and Penny's sword), reckless behavior, and similar sense of humor shown in episode 4 of Volume 3. As for how it happened you could come up with dozens of scenarios. Maybe Summer and Qrow had a one night stand before Raven suddenly left/disappeared and Summer married Taiyang soon after.
