I'm probably going to catch flak for this, but the Vince/Shane feud from around X7 had a special place in my heart. I watched my mom go through hell because of an awful father. So to see Shane get revenge on an awful father made it like....my power match or something. The plot line of Linda being mistreated was like my mom and seeing Linda kick Vince in the balls sent a rush of adrenaline through me that I even feel watching it today.
Now I don't condone the humiliation of Trish and thought it could have been left out, but even Trish turning on Vince was a cool goosebump moment.
It's really cool when you can see real life elements come out in storylines that even sometimes help you feel better about a situation.
On a side note my mom was never put in a mental hospital or had a nervous breakdown. I was just comparing it to being mistreated.
