but you brought in the cold
Tom asks you to officiate his shotgun wedding.
And you say yes.
Because you said nothing when he stopped flirting with you so openly.
Nothing, when he and B'Elanna started staggering their arrivals.
Nothing, when he stopped leaving Sandrine's unlocked.
Later, you sob so hard in your bed that Chakotay uses his emergency override to rush into your quarters, pleading with you to tell him what's wrong. But Tom and B'Elanna haven't told anyone yet, took the Flyer out for a 'honeymoon' and only Harry saw them off.
You say nothing.
There is, after all, nothing for you to say.
