@2:13, I wonder if they are talking about the fencing scene, because there are only two scenes they came across with each other: the other one is when at the beginning, at Elizabeth's court, the Queen and Lord Dudley (Joe's part) walking along side that corridor lined with counselors and knights of shires, they came to the Darnley father-and-son duo who kneelt before them. Jake said the fleeting moment was very powerful and almost came to head on. In the fencing scene, we can only see Joe was dueling very intensely with someone. Presumably that someone was Jack's part, aka Lord Darnley, future King Consort to Queen Mary.
