Panel 1: We'll have to wait on that. It seems he's going over their financials. It seems that with Mike and Liz being O.K. (despite being sooooooo poor) and with April's RESP not totally gutted, they should live quite nicely on the tribute they exact from the beneficaries of their generosity.
Panel 2: He also notes that with both of them working part time at their old jobs, they can maintain a decent lifestyle as long as they exercise caution.
Panel 3: She points out they've always been careful.
Panel 4: He answers her by saying they have to actually be careful and not just say it. Her reaction is one of sadness because she'll have to abandon her beloved false economies. His similar look of concern means he's mourning his inability to make impulse purchases.
Hypothesis: Their friends will be convinced to pay for the Settlenuptuals out of the goodness of their hearts and not at all because of emotional blackmail. Also, thanks to John's stupidity April's going to take it up the ass again and be made to like it.
ETA: This story arc needs a name. Since it's so much like the Housening because it's John's stupid whim and everyone (especially April) will suffer the consequences, I propose the Retirening.
