According to the structure of the university at the time, Thomas would have entered the Scots College there; the fact that the subscription was of Scottish officers indicates that that is the most likely possibility. If true, it shows that Brus' motivations were not entirely altruistic. The Scots Colleges abroad were being used as training and staging areas for Scottish priests intended to enter Scotland in the wake of the invading army and play the most significant role in its reconversion. The failure of the invasion left them in place (without much work to do other than intelligence and conspiracy).
