The moment Lara found Ren, they immediately went into a room, and had a bit of fun with each other. It has been a few days since Lara last saw Ren, so her enthusiasm as they were doing it, was tripled.
Once they were done with their playing around, Ren asked Lara if she has done everything on the list he given her. Lara happily reported all her achievements, and how she has done everything on the list without any problems.
Ren who was listening to Lara's report was quite interested in the way she handled the fallen nobles. Ren remembered that he told Lara to ask Kithra for help for this one, yet though Lara didn't explicitly say it, Ren could guess that the first and last attempts to persuade the fallen noble family wasn't done with Kithra. Knowing Lara she most probably did that, since she wasn't comfortable asking Kithra for help.
