Thank you for your kind words. 

The song is called "Kissing Scars" by Elephant Funeral.  https://freemusicarchive.org/music/Caleb_Lemond/The_Learning_Curve/Kissing_Scars...

The last achievement is called "The Voyage Home" after Star Treck 4.  Here's your hint... At one point during the game, One of the characters who is talking on a phone, while the phone is in their hand by their ear, it seems to dissapear for like one frame as if the character is holding a cloaked phone. mouse over where the phone should be and click it to get the achievement.

She will make a reappearance. Not going to say in what way, but yes we'll "see" her again.

I do intend to include it towards end game...

not really, there is a bitchy wife/ex-wife, but her role is very minor.
