Did Peter drop Matt in Africa for a specific reason or was it just a random occurence?

When looking at the paintings the "Spirit Walker" painted, the woman Matt is standing with looks an awful lot like Daphne. The short bleach blond hair is what I'm looking at the most.

I noticed in the last couple season's commentaries Greg Grunberg commented that he was constantly being told not to loose weight, and stay plump, "eat more donuts". Do you think his walking through the hot plains of Africa will give his character an exuse to be thinner from now on?
