Odds are that the unidentified man is Kyle's father, since he tells Kyle about receiving news of an incident at the nursing home involving his (Kyle's) grandfather, and since I'm thinking that Roswell isn't the kind of show where neighbors drop by with that sort of intelligence. Pops tells Kyle to go to the nursing home and deal with things; Kyle looks bummed, and Dad bolts. The bell rings. Liz jumps up, grabs her "new to you" circa-1972 video camera, and goes over to ask Kyle what's up as though she didn't hear everything. They stand in the doorway to talk, blocking everyone's way as they try to leave the room. What's with these people and doorways? Modes of egress are never suitable locations for conversations. Just move on through, folks, and don't loiter.
Four hands, two watches, and a ring in a box. Jesse's giving Isabel an engagement ring, and also placing words into her mouth. She's too breathy to finish sentences, so he's saying what he wants to hear. Isabel: "I'm, I'm " Jesse: "Speechless." Isabel: "It's just, just " Jesse: "Beautiful." She says that it's gorgeous, but that she can't Jesse: "Believe it?" No. Down, boy. Isabel can't wear the ring, because, although the ring is perfect, Jesse is perfect, and everything is perfect (if that is indeed the case, she's one lucky alien), the ring announces to the world that they are engaged. Jesse reminds Isabel they are, in fact, engaged, and then he realizes Isabel hasn't told her parents. They're holding hands and drinking out of humungaloid glasses with Crazee Straws, which are by far the most interesting things in the scene. Isabel mentions that her parents don't even know she's dating Jesse, but promises to tell them that night. Then she goes all girly over the ring again.
Kyle and Liz, walking up the staircase at the nursing home. Kyle explains that Grampy spills a lot of stuff (like those old folks do, ya know), like soup, or other spilly stuff, and that as soon as they, like, clean it up and stuff, they can go home. Um, don't nursing homes usually employ soup-swabbers? Just a thought, but if Kyle has to hotfoot it over there every time someone spills a little soup, then he's got to be seriously lacking in the life department. They're still walking up stairs, so this place must have several floors, which seems odd in a nursing home, since, if old people spill, they probably also fall. Liz, who follows too many men and asks too many questions, wonders why Kyle's father won't clean up the soup, and Kyle tells her that his dad hasn't visited in over a year, likely because Grampy lost his job searching for aliens and ruined Kyle's father's life. Liz stops and gets all educational, reminding Kyle that there are aliens, that his Grampy was right, and that Kyle's dad knows this. Kyle warns Liz not to start pointing out the ironies in his family life, as they never cease. He walks off, leaving Liz perplexed by the word "irony."
