so i don’t know exactly what kind of relationship these two have now but they probably knew each other pretty well when joe and carrie dated. i think jane was really hoping that colin and carrie would be a thing and when that didn’t really take off, she was disappointed but she mostly wants carrie to be happy? so she was probably really supportive of carrie and joe’s relationship?? buuuut we haven’t really chatted yet about how it ended so i don’t know how she feels about joe now. but if it ended on good terms, then these two could potentially be friends and maybe carrie/jane/joe are all friends????
