Saving "THE ASSIGNMENT". Rosalind Chao did a fantastic job as the creepy possessed wife. And, of course, Colm did a great job here. I always did find it funny that this was the exact reverse of what they went through in TNG's "Power Play".
And bonus, Rom got to do some stuff... enough to get him a promotion in the Engineering department.
(Side note: I also found it interesting that on DS9, only Bashir and O'Brien had their birthdays celebrated on screen. Maybe coincidence...)
