Yeah, sure, some people remember Chris. But mostly with a wistful what-might-have-been or an annoyance adopted kid was tossed for a biological one or as a story that makes Jon's speed-aging worse/repetitive. I liked him (particularly with Thara). But I don't see much clamoring to bring him back, and when they decided Lois and Clark should be parents again, Chris was not tapped for the role of son.
