True. Do you remember if she found the pic, or if he gave it to her? I.e. does he actively know she's looking for her mother? (I'm too lazy to search through the episode right now.)

As for Qrow, he's an uncle, and would also be privy to the situation. Much like a father, he would want to protect the girls from getting too far into trouble, and thus serving as another protector/overseer.

Also keep in mind that Taiyang recently left home again (which is why Zwei showed up). Why? Maybe he figures Yang will be more adamant about finding her now that she's older/has more tools at her disposal, and decides to seek out Raven himself, finds her, and hence her recent appearance for a 'talk'. Maybe he heard rumors Raven was on the move again and wished to seek her out once more now that Summer is gone and he's alone, still wallowing in his loss.
