Guess it's still anecdotal evidence at this point. I messed things up twice by now and on the first PT it made Gale whom I did not speak with enough think romance was started. On the second PT Gale was cold as an iceberg up until the untimely Weave scene (that happened before cam celebration). And after "no" he returned to his indifferent iceberg state. Yet the game assigned Wyll as a secondary LI without a single flirting line between the characters.
The game system is too complex for its own good. Though, that little touch of chaos makes replays even more interesting.
