I have trouble understanding the usage of "only" in this scenario.
I was watching the Walking Dead, and I came across this scene.
"How many blood transfusions did you get?"
"2, only 2.
Is "only" used to say that the speaker thinks that "2" is very little? I'm unsure because they gave off the impression that '2' in such a short time is a lot. Though, I've also thought that "only" is used to imply that you think something as very minor (very little). Am I wrong?
