Today I talked to the Advisor. Are we moving soon or not? Can I leave? Ever?
Well, yes. Because it turns out, when I said "I have to leave by the end of August and here's how I plan to finish my experiments by then...
... he took it to mean "I am leaving in August no matter what and here's how I'm doing it."
In the event of reviewers, I may have to fly back, but given that I couldn't care less about paper acceptance as long as I get to graduate, perhaps I can convince Advisor to pay for it. I'll come back in the fall to defend.
I could hardly be happier about this.
