When Vivaan was still alive he did ask Gibson about future plans but nothing was set in stone just yet. Gibson could have done this earlier but he must have waited til Madilyn got better at parenting. She's getting close to maxing out the skill. So...
They went on the Windenburg island they had looked at before. It was a beautiful place.
Unfortunately Madilyn wasn't feeling her best.
Still, Gibson gathered all his courage...
And got down on one knee.
For a moment Madilyn forgot all about feeling sick and felt the love.
She said yes to his marriage proposal.
Sealed.
Happy times.
And then the illness hit again.
She managed to pull out one more smile.
And then they rushed home.
Madilyn went to take a nap to fight the illness while Gibson made her tea aswell for when she wakes up.
Oh and later on...
Somehow Gibson got into a hysterical mood. Thankfully he's still alive!
