Here's a closeup of the 2-way. Note how only two lines of froth emerge from the 10 incoming lines to continue towards center of image. The area circled in blue shows the next step towards the molecule, a '4-way' crossing (up from the 2-way). Note that there are many other molecules hidden in this picture; red circled areas show where some of them can be found. However, all of the molecules circled in red are further away then the one we are currently zooming towards. Once you think you've located the point of a molecule it's important to stick to it when zooming.
