I think he might just avoid it...although there's a chance he could be a throwaway second nom for some.
There's a good chance that Chris, Danielle and Ashleigh might not nom him as they'll feel sorry for him..while his former friends might not want to fully go against him. Then again they may not want to reveal their full nomination hand and Marlon is a good out.
I think the best chance at him being safe might be if enough people nominate Steven.
Chris, Christopher, Ashleigh, Danielle and Mark could all potentially go for Steven after all those chants....Marlon would be smart to as well if he really wants to save himself.
Of course the whole eviction could just be to a house next door...something feels off about it at the moment.
