Guys if want to see the new content with Alex and Tasha do NOT follow the walkthrough exactly.
I also found something new, messing around. After Day 69 when David asks Tasha for the BJ and she turns him down, ask her about the cottage. You will lose Relationship and Passion with her, BUT if you ask her again, the next day and your relationship is at least 30, you will get the option to tell David not to take her along anymore. You ask him, and David gets pissed. You can then go to Ala and use her to get David to stop taking Tasha along. After that, talk to Tasha, and Alex, in the most clinical way possible, will say he wants them to be in a relationship. Tasha tells him to visit her on Friday nights when she is in a good mood.
This is an alternate way of fucking her for the first time. It actually works better story wise than just flat out asking her while she's blowing Alex. This also means you can skip the grind until 15 passion.
So TL;DR, there is an alternate way of getting Alex and Tasha together, it has to do with him getting her out her sexual harassment weekends.
It's not great story-wise, but it's a hell of a lot better than the grind.
One note, if you do this BEFORE the ability to spy on her in the bathroom (but before bathroom sex) you won't see those specific scenes.
Uploaded a save just before David gets shot down on Day 69.
