Since both Stan and Aaron vehemently deny texting Olivia about Mark's drinking, it may have been one of the 3-star men that were stalking him in the FBI building in his flash that saw him take a swig. * Perhaps one of those men were in Washington during Gimme Some Truth, recognized him, found out who he was and texted Olivia. Not sure why they would repeatedly text her more than once, giving the FBI more opportunity to trace its origin. * Or one of those men overheard him in the bar in D.C. yelling at Stan that he was loaded, knew who Mark was, and saw to it that his wife be notified.
