Hi, long time lurker here, just wonna give my 2 cents about this all FB mess LOL,
THIS !
Why should Arrow viewers who don't watch the Flash "accept" that something that happened in a show they don't watch affect their show ?
Apparently there's been a DR SDCC interview where he's "kinda, sort of" babble that Baby Sara could "become" Baby Connor, how could viewers who don't watch LOT even "understand" the writers reasoning behind the twist ?
Why should Arrow viewers waste their time watching S5 if some of it could be erase when Barry fixes FB ?
I'm sure the writers think they're being super clever and as usual MG gonna be totally surprise by the backlash that will probably follow ! That could actually be way more entertaining that FB !
