Not only do the articles point to them being enemies, there are other rumors that Tiger Lily is one of the many maidens that Killian was with, and that he likely did something to break her heart. (That would be consistent with Killian's character where women are concerned). So having TL be Killian's Mom just doesn't make sense.

But I like the thought that they could bring some resolution to that. However, I would propose that what happened with Killian's mom is simple. My headcanon is that Killian's mom died during childbirth, leaving Brennon to raise 2 boys, something for which he wasn't equipped. Which is why he resorted to shady business, and ultimately sold the boys. And if you look at Brennon's second marriage, it has a similar story (Liam II"s mom dies when he is little).  And because of this type of resolution for Killian's mom, there is really no need to actually show his Mom, they could simply reveal this story in dialogue.
