To make matters worse, she hires an expensive lawyer and sues for a vast sum. This turns to horror when their insurance company cancels their policy via a loophole, which could lead to Ida evicting them from their own home and taking all of their belongings due to them not being able to afford the out-of-pocket costs. The boys band together with Piama in support for Hal and Lois. However, upon learning that the family has no insurance, the lawyer refuses to aid Ida (since he will not make but pennies off of the settlement), who immediately decides to leave before she can be kicked out.
