Which Criminal Minds season is this episode from?

I don't really watch Criminal Minds so do not know their names.
The group goes to New York for solving a killing spree. But turns out
there's more then 1 killer. They think its a kind of terrorist group.

The blond girl announce to everybody that she is pregnant.

And the black dude is suppose to get the job of the chief if they
don't solve it.

So which season is this episode from, Hope I gave enough info about
it.
