Everyone in this show should be thanking Gigi.
They were all dead in the water before Gigi showed up. The only one who really had anything was Flash being Lady Gaga's guitarist.
Gigi put them on the map again and it was nice seeing the band slowly come back into the spotlight with Johnny's lyrics and Gigi's vocals in season 1. Now season 2 isn't even about their band but them all going in different directions when none of that wouldn't even have happened if Gigi didn't show up. Ava X, Charity songs, Broadway plays... none of this. They have definitely lost their way with the writing this season.
And what Flash and Ava did to Johnny and Gigi was disgusting. If they want to be together, great. Have the balls not to sleep with each other before telling your significant others that you want to be together. And then don't act smug when Gigi and Johnny try their best with bull crap ways to get over them.
