Burke also was not born rich so it would fit, but the reference to a past relationship of Jade's makes me lean toward Tybalt being her natural son.
beyond that we know of Sage's difficulties in relating to his mother on romantic matters, while we see jade very affectionate and expansive with Tybalt.
But we don't hold that against her.
Idk I would Jade loves both of them, she even tells MC she put her kids over her husband, and even Sage if you tell her about Chad will mention her mom did warn her.
Honestly, another thing I find interesting about Jade's route is how the game gives you a hint about not telling the DIKs about sleeping with her.
I mean the whole point that Jade has been betrayed by Cathy and her husband, and she trusted MC enough to not show anyone to the point MC was having second thoughts about it.
The consequence of showing them is that A either a DIK or The same person (That posted Cathy Pic) sends the sex video to Burke.
If you decide to delete it, then there no one finds out.
So, I have bad feeling Burke will blackmail Jade and even MC with that photo. It would be worst if you chose to date Sage and dump Jade and Burke and have Blackmail of it. HOBOY MC is a whole fucking family dilemma.
