Our reading
An editorial interpretation.
The speaker repeats “arousing” and strengthens it with an unexpected adverb. “Violently” makes the response sound forceful and disruptive, going beyond ordinary excitement. The pause between the two descriptions gives the second one extra weight, as though the first word had not captured the intensity.
