In Mary's mind, Terry can't even begin to fathom why she never told him who his real father was, yet Catalina Flores showing up in town after Nightwing reappears brings everything rushing back. She chooses to confront the past, even only partly.
Disclaimer - I don't own Batman or Batman Beyond. This is working with my alternative head canon for Terry's origin where his biological father isn't Bruce, but someone else. This varies from my other stories featuring said headcanon slightly in the fact Mary/Helena knows Nightwing's not really dead, although the rest of the world thought so.
The third round of Write to Rank involved "an epic banter between good and bad", but I also found myself currently thinking about how DC never addressed Tarantula raping Dick, so I ended up with an epic banter with multiple "goods" chewing out the "bad" on this one. Not quite the result I wanted, but it works.
