Unknown Tenants and Landlords

Unknown Tenants and Landlords

Long story short. My heating bills over the winter were insanely expensive, so we took in another roommate and didnt tell our landlord (cause he was going to charge us another $100 a month). Now we are moving out (already basically have really) and our lease is up June 30th. The roommate says she is still looking for another place to live, but has yet to find a place. What happens if the she doesn't move and stays there? And the landload finds out that she is there? I'm just stressed that she won't leave and the landlord is going to give us heck. (Not a nice landlord anyhow.) Also worried that she isn't going to clean the place after she moves out. My brother said the worst the landlord could do would be keep the security deposit and if the unknown roommate was still there, it would be the landlords issue... I'm also worried that the landlord will randomly show up one day and see us not there but see her there. Anyone have experience with this?? Or legal knowledge on this matter?? Or advice?? I'm stressing something fierce.
