It's Arlington Heights, not Arlington.

I caught that. It seems to happen fairly frequently with place names--they're almost right, but not quite. For example, in "100" they go through a list of MD cities in their search for Foyet. Emily mispronounces Bowie (I seem to remember Vortex vehemently shaking her head over it). Only newcomers make that mistake. Every last one of them would know how to pronounce it correctly.

They've also said Silver Springs more than once (It's Silver Spring, FWIW)

And yet, during ...A Thousand Words, when it was set in Tallahassee, the locals had southern accents and Spanish moss hung from oak trees. Plus, they had the correct surrounding towns and highways.

I was fairly impressed.

Reid volunteering to conduct the interview and his rationale for it had me fist-pumping and declaring "All hail the Beta male!"

Seriously, the Beta male is my favorite character archetype and MGG plays it to perfection.

I believe that over the Summer Reid's hair took drama class - it was emoting all over the place.

Why isn't there an emmy for most emotive hair?

They did a good job with Milwaukee in that ep with the brain-tumor guy.

So it's just the DC Metro area that they can't get right. I think they need to hire one of the DCistas as a consultant.

I think they should hire two.

That way, easier to capture and subdue to make absolutely certain the details are right.

So it's just the DC Metro area that they can't get right.

Yeah, like in Sex, Birth, Death where Reid meets Nathan on his way out of the metro. 1 - the metro doesn't go to Quantico (which is a good 40 miles from DC) and 2- the metro that he was coming out of is no where near the FBI building.

have they totally dropped the storyline of Castle dating his ex-wife again?

They mentioned it explicitly in the episode where his mother's boyfriend dies.

Castle mentioned that his ex was still high maintenance while Martha was expressing doubts about actually marrying Chet, and Alexis was having her romantic ideals crushed by her family.
