In short, if you're not a dick you're forced with the mother, and I wouldn't be surprised if the corrumpt route eventually leads to another forced scene (as the mother freaked out, but mc was totally going for it..)
Not sure exactly but eh did not in this reboot anyways, did not use his darklight to actually get with his mom in any shape or form, he did however use it on his gf.. at least for getting the scene where she freaks out that is.
So a few key things I did at least that made sure I got this scene ( replayed today and tried a few choices to see what is required to trigger it )
Must use all the dark light for your benefit, as in. Therapist Office, Save the thief,also other choices that must be made are, Go for brutal and or killing options or corrupt ones, for example at the start agree about money and power, don't betray em, mention the mafia to mom, shoot the dude straight up in his face. Make sure to the choice is to kill leaders instead of going after businesses, send him to the lightbringer instead of getting asian guy's family. Do not forgive him, when talking in the office with your subordinates, make sure to choose to corner. That type of thing.
What you do NOT need to have for the corrupt path is, does not matter about the cop lady so ntr or not does not matter at this part same goes for the gf, ntr or not you can give in on this one, I have however made sure that I protect the Mom at the start, I might give a try to make that different to give it a try but am tired right now.
So even if you are on the NTR path so long as you are corrupt and bloodthirsty you will get the scene with the mother actually having a meltdown and him forcing to calm her down using dark light and no kissing happens.
Not sure if you were to go on a full NTR path that it would still trigger, but a good indicator is that when your mother visits your room the second time and has a conversation with you where she cries, it means you are on the correct path and if she goes to apply for the school and has a normal outfit.. you are still on the right path. Make sure to not forgive Carl and not be a wimp.
So you can get it on both the Non NTR and on a mixed NTR playthrough. The big factor here is how corrupted you are or not.
PS Edit : Her freaking out is nothing to do with you hitting on her as that is not exactly what you are doing, her freaking out is that she is afraid of what you are becoming and her losing you like she did your father and all that is bringing her to a mental break down, Remember from the start of the game it seems that in that household everyone with the exception of red haired sister... they all have had mental issues.
