In #1 as a passed hand there is no force unless you are playing 2c as drury. So 2S would definitely be a reverse. As an unpassed hand and playing 2/1, 2c would be gameforcing, so 2S would not be a reverse (as I play it). Playing sayc, I think many play that 2S over a 2/1 response is also not a reverse.
In #2 I would play 2S as a reverse and if pard had the trap pass type of hand for the pass of 2D, he/she should definitely respond.
