What you said was pretty clear to me at least. I have that user tagged as a misogynist so it’s not unusual that they’d go out of their way to defend incels for no reason.

For what it’s worth, it’s unlikely that the incel in question would have the location of both those people in the first place. Generally, location sharing is done among friend groups and not entire peer groups, so it’s unlikely the crush and the person they were seeing would have both shared their location with this other person unless they were all close, which is not the case in my experience.
