If you're still stuck on how to answer these questions, here's my two cents on what the answers could be...
How could I get you to talk to Rudrick? At this point, Skobeloff has just enough of a rapport built up with Garrock that a successful use of the CONVINCE SOMEONE move would be all that is needed to get him to see Rudrick
How could I get you to talk to Sunglow? The situation with Sunglow is a family matter. And as such, only one of Garrock's family would have any real chance of convincing him to go see his mother.
I'll wait until Vertigo posts before I say anything but, err...
The reason it's taking me a while to think of answers to your questions is that Skobeloff essentially asked "How do I get Garrock to do the two things he really doesn't want to do?"
Seriously, I can't stress this enough: there's not much that Garrock would rather do less right now than talk to his family. He'd rather single-handedly take on an army of giant spiders than do that.
