Each morph has zero or more submorphs which are ordered front-to-back. The chain would consist of (recursively) the frontmost submorph whose bounds contain the event point. So, it would look like:

1. The World
2. the frontmost submorph of the World that intersects the event
3. the frontmost submorph of #2 that intersects the event
4. and so on until there are no submorphs that intersect the event
