I mean, it's immaterial. We are through. If Ireland win, then we are through. If Scotland win with a bonus point and Ireland get the 7pt losing bonus point, we are through and Scotland are out because their points difference isn't big enough. If Scotland win with the bonus point and Ireland get a try scoring bonus point, but the margin of the loss is (I think) more than 12- then Ireland are out (because their points difference decreases and we are only 5 behind. If Ireland gets two bonus points (one for within 7 points) then again Scotland are out, because it would be just us tied together, and we beat them in the head to head (plus our points difference would be better).
I can't think of a permutation where we go out from here. Pretty sure we are locked in.
