I agree with Dany, it's plausible that Ma slept with Gallerian to purify herself even further. We already have an example of magical mechanics surrounding birth (Banica's baby was a "vaccine" due to having a weaker version of Grim the End's poison). Maybe siring Gallerian was able to purge some of whatever she didn't want inside of her, and by having a child with him, the child they sired (Nemesis) could purify her even more than just having a child with any other man.
