Thank you for sharing!
I find it fascinating to read how people who know KA describe her. According to one of CS's cycling friends:
"He liked Armstrong; he described her as beautiful, a little intense, and—as he came to realize—competent with money in a way that Strickland didn’t care to be."
...she seemed happy with her relationship. “She was in love with Colin. She wanted him to be—you know—the one.”
...once described herself as being too jealous to ever have agreed to be in an open relationship.
We also learn a bit more about the timeline. On October 23rd, Mo and CS were at the same race. CS brought KA along and when they approached Mo and her friend/fellow racer, KA was "pointedly unfriendly". Mo's friend is confident that Mo and CS were still just platonic at that point. Three days later, Mo was in Austin and CS took her to a regular local cycling event, where KA knew all the female participants. That evening, Mo received a call: It was an unknown number, but she took the call. A woman told her, “Stay away from Colin.” During that visit to Austin, Mo and CS even took a trip together to West Texas. When Mo got back to California, she told her friend about what happened and her friend (who actually has her own history with CS) tried to steer Mo away from him. By May 7th, CS had just completed a solo road trip which included California; while there, he and Mo were in the same race and the two of them did a training ride together.
Lastly, Mo's friend said something that I hadn't considered before:
... unnerved by the thought that Wilson, while launching herself as a professional racer, had perhaps felt obliged to keep in touch with Strickland because of his “access to brands and sponsorships and connections.”
