And I’m sorry it took me so long to get to your question. SHAME. Colleen is intentionally vague in the series because I wanted to focus on Kit, but the clues are there. She was a warm, caring mother, but maybe not the most equipped. They never had much, but she always made Tory feel safe. And that’s why losing her was such a blow. She thought that her mother was all she had, until she met Kit.
