Logan was right to do this
I understand that Rory was initially caught off guard when Marty pretended not to know her - however, she should not have waited as long as she did to tell her the truth. She was actively lying to Lucy, and I’m glad Logan didn’t go along with the lie. Marty was a jerk to put Rory in that situation, but Rory was also wrong to delay in being honest with Lucy.
