Did House really had a romantic relationship with Ali, the 17 years old girl from Fresno, in season 3?

no, but he wanted either her, ou his old bloodstained carpet. he ended up with the carpet, and ali ended up with the diagnosis of spores.

She was infatuated with him. There was no romance though, she was in 3x03 and 3x04, if toi want to see.

No,she was flirting with him and he was just having fan..I think..
I hope that helps

not really

not really, but it made cuddy really, really jealous!!!

Nah,I think he just flirted her only becouse he wanted Cuddy to be jealous,nothing much!

Nah, she had a crush on him and flirted with him. House was having fun so he did very little to stop her, but he was never gonna do anything about it while she was a minor.
