There are two versions of this game, online and renpy download.  The downloadable game has more options and content than the online version.  This walkthrough is based on version 2.0.

There are four scenarios from Something’s In The Air that are represented in Rachel and Ariane:

PC dated Ariane and ended in a threesome with Lydia (See SITA ending Tequila Shots):

• Say “Yes (Player took her to the movie)”
• Say “Yes, once a few months ago (Player had a threesome)”
• This is the lone scenario used in the online version.
• In this scenario, Ariane has been intimate with Lydia, so Lydia stops by to say hi in part 2.
• Say “Yes, Ariane should go with Hiro.” Ariane has sex with Hiro, Rachel meets Ariane’s mom, Ariane goes to an orgy and has sex with Heidi. Rachel has sex with Tassiana.  There is a big emotional scene at a cafe after Christmas.
• or Say “No, Ariane should stay with Rachel.” Ariane follows Rachel to the meeting with Ellison, where she is surprised to meet her mom, they talk things out. Ariane goes back to the bar to wait for Rachel, while Rachel meets Ariane’s mom. Ariane and Rachel bond over the experience.
• Ariane calls Lydia for advice on the plane ride from New York in part 5.

PC dated Ariane but did not end in a threesome:

• Say “Yes (Player took her to the movie)” or “No (Player took her to a different movie)”
• Say “Just some experimental making out in college (Player dated Ariane, no threesome)”
• In this scenario, Ariane has never really been with another woman before, meaning Rachel is her first time.  There is no meeting of Lydia in part 2.
• In part 3, Rachel takes Ariane’s photo, Rachel always calls Paula for help, so the option to arrange hair and makeup for Ariane is not available.
• Say “Yes, Ariane should go with Hiro.” Ariane has sex with Hiro, Rachel meets Ariane’s mom, Ariane and Rachel go to the orgy together and leave pretty quickly.  There is a big emotional scene at a cafe after Christmas.

• In this scenario, Ariane had some foreplay with Rebecca. Rachel reveals her last time having sex was with the PC in SITA.
• In part 3, Rachel takes Ariane’s photo, Rachel never helped Paula out making her storm, so the option to get Paula’s help with cloud cover is not available.
