So, Janeway and Chakotay seem to have a degree of romantic chemistry and tension in Seasons 1-3 that seems to fall off in Seasons 4-7. There are many reasons why this happened from a creative standpoint, some obvious, others conjectural. But what's the fictional, in-universe explanation . . . I just re-watched "Scorpion Part 1," and I'm wondering if (a) this could be viewed as the moment it all fell apart and (b) the writers might have even intended as much. Janeway and Chakotay seem very close at the beginning of this episode, Chakotay promising her that she's not alone, Janeway telling him that she can't imagine being without him and giving him an affectionate little pat. Then they disagree over the Borg alliance and Janeway says that she really is alone. I'm wondering if that romantically cooled things for them and for her in particular, even after the situation was practically and emotionally resolved in other ways.
