He will not let happen injustice to Priya, so him asking Priya to leave house is very very unlikely.
Niharika will not think of NUTZ now as per her info she is expecting and family loves her a lot. So Priya kicked out will not affect NUTZ.
But with all consideration of Drama high point I guess -
Ram may ask Priya to stay in one of his other flats / houses or may even ask her to leave for some days. When tells this to Krishna that because aske asked about her, Ram asked Priya to leave house... then Krishna may step in and solve this mystery.
