Yes, it was a reflex.

in consequence of the missive, Lydia's elopment, penned by Nikki N
She didn't have reflection : maybe reflection would have advised her to conceal Lydia's elopement from Mr Darcy, for instance in the hope there could be a mistake or they may be found before Lydia had fallen "an easy prey".
She let her feelings act, and her feelings guided her to tell Mr Darcy everything.
Of course Mrs Gardiner didn't know how it came that she announced him the elopement, thus her "And are they upon such terms as for her to disclose the real truth!" : we can suppose that she believe more than what really is.
But are her feelings so wrong, in telling him all what she tells?
Isn't she the perfect damsell in distress? What can be the effect of such a vision on a noble knight? Why not whitening? ;-)
