Plan A - Sin Houng comes back, 7th snare place filled, all goes as plan.
Plan B - Sin Houng doesn't come back, 7th snare place empty, 2 people eligible - Lianne, Jessica. Lianne? Size problem. Jessica? Fit, but need to switch. Lianne then comes to tenor. All is solved?
Nope. I prefer plan A, but most definitely we need to assume for the worst, so plan B is starting to over-power the situation. Sin Houng, please come back T_T.
Alas, do your best Jessica.
