JMHO, but I don't think Lucas and Cuddy are right for each other. Is he really the reliable guy she needs for her daughter? According to Ask Ausiello, it's gonna take Cuddy a while to figure that out:
Question: The last episode of House was painful to watch for us ‘Huddy’ fans. Please tell me Cuddy will drop the stupid PI and give House a chance? —Heather
Ausiello: Looks like we’re stuck with Lucas at least through early February. If it makes you feel any better, rumors that House’s mental institution lay, Lydia, will be paying a visit to Princeton-Plainsboro are apparently not true. An insider says there are no immediate plans for Franka Potente to return.
