Greer is mentioned in an IRM proposal for Goodwin Morin. The specific by-name mention is:
With help from Malik Destiny and Greer Gwiffin, who were her teammates on both the Garages and the Society, Morin was able to connect with blaseball for the first time as a source of joy. Even though her team was eliminated, she became close friends with Destiny and Gwiffin and began to have fun learning about the splort.
