Only because it was an house with 1 guy and 2 girls.. They wasn't invited because their move already was decided and that why they invite the actual couple from that house.. But all that meeting was a big scheme to look a happy family after what happened
Unless these ones fuck half the city, in this house they will be totally loss and no way they will get the same attention/posts P&C had in almost 80 days. "Ignoring" houses with less then 2 weeks that suffers from a lot of boom on first days P&C still was at top3
But it's like i said, the purpose for that managers now are getting the money from the trial and then hire new meat for the project as soon as possible
