When you are using parens for the insertion of a blurb -- e.g., (indicating) -- the rule is as follows:
When the information inside the parens is the entire thought, it is capped, and the
punctuation goes inside; when the information inside the parens is part of a larger
thought, it is lowercase, and the punctuation goes outside.
...Q Where was your arm bruised?
...A (Indicating).
...Q Where was your arm bruised?
...A Right here (indicating).
Happy punctuating!
