Sorry for the delay! Crazy weekend and had a rough day. Thanks! I was so happy to find it had been purged.
I don't think a friendship would form if Pip perceives Rowan as being less than shouldering his fair share of the load, or if he senses Treasa's frustration. Pip is generally polite and cordial (dare I say unflappably British?) to everyone except for Olga's brother, but it's likely a cool relationship.
