Peter and Lois are married!...and Brians tried to get somewhere with her before and she hurts him for it, so yeah. Probably Peter.

the answer is peter.Because every time Brian hits on Lois she turns him down except for the cast away epesoide where Lois thought Peter was dead and in the end Lois still left Brian for Peter.

i think she will end up with peter

isn't Peter and Louis married? and besides, if Brian and Louis were dating, it would be disgusting!

of course peter brian doesnt have a chance.

peter.. they have been married and each time brian tries to make a move on Lois, she usually never lets him

I think Peter because Lois and Peter are married Dummy.

Peter of course! They are married!

She would pick peter because he is cool

peter because their married and brian always makes little hints that he LoVeS her
