I’ve wondered about this a lot as well. Here is how I understand it:
The Queen Bee has less hesitancy about approaching people they don’t know, due to their entitlement. They purposely latch onto people they see as weak and love bomb them and then start to use them. Some of the people that give them pushback from the start will become their real friends, likely because they are similar. This gives them a large number of friends of varying levels of closeness. The love bombing means an acquaintance can suddenly find themselves in the best friend position.
The Queen Bee always plays the victim despite their own poor behaviour, and because their friends are like them, they take turns supporting each other and not looking at situations objectively. It’s always the other person that is at fault, no matter how much evidence to the contrary is presented.
Some of the Queen Bee’s friends will see what is going on, but since they don’t want to be the one attacked, they will continue to fawn over the Queen Bee. From time to time, the Queen Bee will assert their position when they are surrounded by their friends by being nasty to someone they see as below. This assures their followers that by being with the Queen Bee, they are better off. Had the Queen Bee been alone with this person however, they would have received the love bomb treatment.
It basically comes down to entitlement. They believe they are better and act this way. Other people are attracted to them when they are love bombed and treated as though they are better too. Other people avoid being the one attacked by staying loyal to the Queen Bee.
