I believe he's a nephew and I've found him to be pushy and a bit of a con as well. He's pulled similar things on me, way way way too much food and then, even though still reasonable, more expensive than it needs to be, or ever is when Helena is there. The only bad taste that's ever been left in my mouth there is him.
"In pursuit of joys untasted"
from Giuseppe Verdi's La Traviata
