Thanks Turnbull for your clarification

I am not disputing “Michael went because he needed to get away from Tahoe, for the safety of his family and himself as Michael was the target”

Fair enough!
I was somewhat confused by the $2 million “solely as bait to keep stringing Roth along to the last minute so Michael could find out who the traitor was in his family”
I get it now, chances are closer and better to finding the identity of the traitor ["very close" to Michael, back in Tahoe] in Cuba than Tahoe

Continuing “we'd never met”! charade
