I have just finished binge-watching everything I could get my hands on for Evangelion and it now feels like there is a hole in my soul. But I have a few questions.

Is the NGE ending connected to the rebuild series like a time loop or is it a "BAD" ending and Shinji and Aska are acting as an Adem and Even on tbe new world after the third impact leaving hell on earth.
In the after credits of 1.11, 2.22, 3.33 there are clips that simply arnt in the movies like a half pink and mark 2 with a katana cutting enemys that just dosnt happen.
Do I need to watch true (death)2 on this watch I was told it wasn't needed but then the rebuild movies had the big change in them.

Dear God..
