i finished that new Lego Batman game few days ago and that exact type of dialogues was there too. "hmm it's a piece of portrait, we need the other two to solve a puzzle, hmmm now i found another one, one left, hmmm"
plus constant humiliation of main character as a nice bonus
The only reason the cube is there and why the sword - I'm sorry, the sword ribbons - are talking is for them to treat you like a retard if you don't solve a puzzle within 4 seconds and instantly give you the solution.
That and every moment of silence will be filled with quippy marvel dialogue between the ribbons and the cube so the players wouldn't fall asleep if nothing exciting happens.
