Please help. How do I punctuate the following?
"During the first wave of testing-" Alina flashed quote marks with her fingers. "-most of the subjects blah blah."
or
"During the first wave of testing. . ." Alina flashed quote marks. ". . . most of the subjects blah blah."
or other
(or should I just drop the interruption?)
