Eddie and Nathan were not the only cast members who did not embrace Preston. Perhaps it was Preston who distanced himself. I am making no judgements here, just observing.
Preston said he required a lot of alone time and did not appear to make an effort to get to know anyone and this happened straight out of the gate. It was not in reaction to what became a hostile environment. I am not condoning any nasty comments thrown his way but rather saying Preston was an active participant in his relationships on this show. This did not happen in a vacuum.
