If I didn't read too fast...Harry understood something was hiding in the LeStrange's vault based on how Bellatrix reacted when she saw the sword of Godric Gyffindor. It was supposed to be in her vault along with the cup. She freaked out when she saw the sword. He already had previous knowledge, albeit limited, about the cup.
