I Think I Might Have Missed Something - Tumblr Posts

I’m left with two questions.

Why did they show Dome in the taxi going home to see Tonkla after Great saved him while he was in his 4 minutes?

And how did the woman (who Great killed in the hit and run) doing the ritual affect the story? What was she trying to accomplish? It didn’t look like final rites for her son or anything like that to me.
