There's a lot of information missing from the spoilers: Spoiler: missing info from 8.01 & 8.02 What happened to Sharova and Mr. Green? How envolved were they with the russian mob and its weapons' operation? I don't think it's Cal's shot that caused all the injuries mentioned in the 8.01 spoilers. She might've grazed his arm, at the most. What I think could've caused a strain between them is Cal's lack of trust in Eric's judgment, especially if Sharova turns out to be one of the good guys.
