Yep and I think that obviousness has been a frequent theme this season and not a good one. In the past, most events genuinely had a surprise factor to them, none more so than the Red Wedding or Joffrey's poisoning and that made them great moments. Now one of the clearest ways that the show's writing had degraded is in how obvious everything is. Arya was clearly going to disguise herself as one of the girls and do in the paedo. Anyone could have seen the religious nuts turning on Cersei from a mile away. In the last episode I knew as soon as she did it that the kiss was going to poison Rapunzel whats-her-name. As you say, that little shit Olly turning on Jon in some way was the most obvious of them all.
