Example:
[First panel] I licked a petri dish filled with ebola to see what it tasted like.
[Third panel] I'm bleeding from my anus.
or:
[First panel] I licked a petri dish filled with ebola to see what it tasted like.
[Third panel] And I'm bleeding from my anus.
The first example makes it clear that the anal bleeding is directly related to tasting ebola, while the second sounds like the bloody anus could be coincidental.
I'm not trying to make a point here, I just like saying things like "ebola" and "bloody anus".
