No need for a connection with Matt--Richard knows that the nanos are messing Liz up and he's trying to know more about this (when MC and Richard almost caught Matt and Liz in a bar in 0.18 or 0.19, it wasn't an accident, despite what Liz thought at the time--the place was chosen by Richard, who didn't know in advance where they were going because he was waiting for Liz to move, as he's probably watching her as best he can to see the extent of the damage, and probably try and undo what he can, is anything).
