Pissed for being played by Alan Morgan and laughed at by his grandfather Harold Stanley, Finn went out for his night jog in the cold to train his body.
That cold was nothing for him to stay huddled in the duvet. Since Aria stays indoor without going anywhere after six, he only gets to do his workout and other core at night so his routine had changed from morning to night, and was already too used to the cold.
The regency they were staying in was also secure hence he didn't worry about the dumb girl's safety if he has to visit the gym. But he was really curious to know how the dumb girl maintains her physique slim without exercising.
If not anything, he could at least say she had a healthy routine by her complexion and she never fell ill due to cold. Hence another headache of being worried about her health had off his mind.
