This still isn't private is a point Tidus would make to interruptions, but he doesn't particularly care to. Elidibus can give his disapprovals in his own way, but Tidus folds his arms, no less of a furrowed brow and frown etched onto his face.

It might be more private with the barrier that's put in place - if with the foolish interruptions present inside it - but the situation wasn't exactly any better, where Tidus was standing. Whatever was going on, with talks about thrones and multi-world events being the least connected to him than anyone else in the room.

Did he have a clear clue of the drama? No -- but he was here, and he was going to stick around.
