What exactly is the dad doing if she's the one handling the wall the mines and the clinic? And the brothers are in the front line
Probably the finances but at this point he should just trust it to Liz too since he clearly can't handle it neither
I just wish he kicked the random step mother like he doesn't even like her and never limits her budget? Why is this random woman draining the money and mistreating your "beloved" daughter
