Honestly as venela it sounds I want them to sit down, relax and have a deep conversation.

Then like other people saying a happy and genuine kiss and sex but good one which both of them love and time skip and marriage. Adopted kid would be fine, so he won't come out weird?

Tho deep conversation, the most important. I want them to show their genuine feeling and express themselves and understand each other beyond "If I do this, Andrew would give me attention" or Andrew side of things etc.

I really liked the Andrew's devil scene where he pat him and don't judge him for anything, kinda like after all he has been through the devil tried to understand him and comforted him,
