Since Louisa died Vivaan doesn't have anyone to protest with so Madilyn helped out.

Back home. Gibson was so not done avenging Louisa. He had a word with Vivaan.
Things got heated.
Gibson tried to overthrow Vivaan as the leader of the Goldsmith Gang. He's not even a Goldsmith and he's cheated on the generation 10 heiress when she was alive and disrespected her after her death. He was in no position to be the leader of the family club!
Vivaan wasn't about to take a preaching from the kid though.
Gibson needed solid support in this. The problem was it was only him and Vivaan in the club.
Madilyn came into play again. This time to help out Gibson.
He asked her to join the club and they talked about how bad Vivaan is for the role of the club leader. She agreed.
Gibson went in for another try to overthrow Vivaan again.
He succeeded.
And then Gibson said a few more bad words to him.
Gibson and Madilyn in their new union.
Again dad didn't know what else to do but to cry at Vlad's grave.

Madilyn and Gibson took an advantage of their cute little bond.
Madilyn asked Gibson to be her boyfriend.
He liked it.
...and a little bit more excited looking in this:
Now when normally a fresh sim couple would woohoo after such happy incident then not this couple here. They decided to wait til marriage.

But Gibson needed to get his built up tension to be released...
He was still not totally okay with Vivaan. Gibson wanted him out of the Goldsmith Gang.
The face of defeat!
Gibson got what the wanted. Vivaan was super sad how he should've been after Louisa's death.
Madilyn didn't wanna get involved in all of this so she stayed away as much as possible. Vivaan also pulled back from Oumaima so he had no one to talk to really.
Except Vlad came out every once in a while.
Vivaan got working on their relationship to get Vlad to move into the household properly.
