...what if her purse was too small and she just held it in her hand the whole time?
@yumungmei I thought the same, but so far all the conspiring can be blamed on Pamela though the fiancee is clearly unloyal. Maybe it's just in his nature as a pretty boy.
@jonsmth You'd be surprised. In social psychology it's well documented as the bystander effect. When a large crowd is gathered, responsibility is so diffused, everyone assumes someone will step in so they don't need to act themselves. The result is an entire apartment complex can witness a murder being committed and no one calls 911 because literally everyone assumes someone was taking care of it.
At the same time there's a strong pressure to not stand out and wait until you know what the room consensus is before speaking. It takes the first brave person to step up before anyone else feels ready to corroborate.
