When a speaker resumes speaking mid-sentence after an interruption, what case would be correct or better practice to use at the start of the sentence? As the resumed dialogue would not be a complete sentence, would this require lower case?
"When I was in the military, we had to watch out for scorpions—"
"Oh no, not more boring army stories."
"especially, the small brown ones, that could kill you!"
Here, I believe that the lower case e at the start of the sentence is correct.
