Questions on the A350-900 Economy cabin.

The seats in the first economy cabin seem aligned, but the start of the second cabin they seem misaligned, but by the time they get to the back they are are aligned again.

1) Is this an accurate portrayal of the seats? Depending on what seats are left at T-48 for my next trip next month, my partner and I may both want aisle seats and preferably just across the aisle not an an angle. At the moment, on Q class tickets, we can only pre pay for seats in the first part of the 2nd cabin, ie the misaligned section. I'm hoping at online check in we have more seats to choose from (All sectors currently show 9 for sale in all classes for what that's worth!).

2) If the seats are misaligned and then end up back in sync by row 70, does this mean there is more or less leg room in some seats compared to others?

3) Do the seats in the back row of each cabin recline fully? SeatGuru adopts its usual "seats may not recline fully" approach. Are the toilets a big nuisance here? I can't recall how loud the flushing was compared to other planes.
