Under the watchful eyes of these two pages from Sammy Harkham's Poor Sailor and as a kind of summary of comics silence, I offer the following:
-The end of communication/interaction
-Body language, the tip of the hat to imagery
-Anticipation of communication/interaction
-Effort, work, process
-Emptiness, minimalism (certainly silence is opposed to the splash page. Silence, I think, depends on panel size; a two-page spread transgresses silence by being loud even if silent)
The scene in Poor Sailor: a husband contemplates going to sea with his brother, which would result in abandoning his wife and their unfinished home.
I'll finish with Chester Brown's Louis Riel. This typical-for-Brown four-panel sequence dramatizes at least a few of the modes I've entertained above.
