Lara hates Wendy
She hates Wendy because she feels Wendy has the inside edge on Axe. She feels Wendy has the power to manipulate and influence Axe on just about anything. And the funny thing is Wendy knows that Lara is weak and needy and really lets in sink in that she is the one who made the decision to not see Axe on the job.
Lara is supportive of her husband but it looks like she is totally fed up with the lies Axe keeps feeding her about his decisions, especially those involving Wendy.
