Their last words change if you romanced them and choose them to be Fire Team Leader 2 (during the Long Walk):

Normal Thane: "There were too many. Shields couldn't hold up." Romanced Thane: "I hear it, a sea. You look beautiful, my siha." Normal Jack: "Too many... Tore me up. How'd you talk me into this? Heh... I wasn't supposed to care." Romanced Jack: "Too many of them...I knew I'd get hit on this job. I was too happy...too happy with you."

Hope that clarifies it. :)
