When she dies, all bets are off.

Nothing like putting aside your differences in a crisis with the full intention of bringing them back to the forefront when it, or your mother, has passed. Maybe I read the strip wrong. Maybe it’s a more positive thing than I think it is, but the way I read it, there seems to be an unspoken, “…for now,” lurking in the shadows. I think it's the bold words of "It's what Mom wants." Sounds a little snippy.
