SPOILER question

So early on in the campaign Marcus is having a “discussion” with Jin, the fertility program gets mentioned and Jin states it gave Marcus his son. Jin then mentions that Anya volunteered for the program, BOTH TIMES. So has Marcus got a second child? JD’s sibling out there somewhere? Died maybe? Seems like a big deal to not have mentioned in 4 tbh

I think Anya died while trying to have a second child. I doubt it was a successful pregnancy.
