S2E8- WHEN did Cobel….

When did Cobel invent the severance chip?

It appears that she left home when she was 12 years old as 12 was when the last height marking that was taken in Sissy’s house. She worked at the ether factory since she was at least 8, meaning she worked there at least 4 years. Let’s assume she leaves for the Eagan school at age 12.

I can’t see an 8 to 12 year old drawing up the plans for a severance chip. And she had not yet gone to the Eagan school. So, her notebook was at Sissy’s house. She came back at some point? Left her notebook there? And at what point did she come back and leave her book there? Judging by the notes and drawings I would guess that’s a college level education.

What are your thoughts?
