Understanding which-way patterns in DCQE

    Figure 3 of the below shows 1 blob.


    Other illustrations show 2 blobs....i.e. one for each slit.

    When does 1 blob happen and when does two blobs happen?

    Figure 3 is just a thought experiment. Supposedly the photons no longer act like waves if they emit photons that are detected in the cavity and make a blob on the detector.

    Where do you see 2 blobs at?
