[Avengers MCU] In the first avengers movie when Loki was captured and Black widow was "interrogating" him he mention hulk (that you brought a monster) and black widow was all like ohh that's the plan. WHAT THE F**K WAS PLAN ?

If i understand correctly his plan was to use the alien army. There was no need of hulk.

I took it as Loki's plan was to the sceptre and disband the Avengers. His plan was to let loose the Hulk to not only cause a diversion so he could the sceptre but have them fight. 

Plan almost worked, except he killed Coulson.
