I'm pretty sure I intended that red mark on Ellen's face to be an injury of some sort, but that winds up not really holding water. I sorta like to think of it as goop from one of the Goo's read eyes.
With that said: Ew.
Ellen is technically sort of right. No goo means no meeting Grace, no Tedd taking the TF gun to Elliot's house. One could sort of argue she gained everything given that she didn't exist prior to Elliot touching the diamond, but it sure doesn't feel that way from her perspective. Having all of someone else's memories will do that to a person.
