The second season of “Jack Ryan” is 99 percent totally solid, but it’s got one major quirk that can be pretty disorienting for fans. That quirk being the complete absence of Cathy Mueller (Abbie Cornish). And by “complete” I mean she is neither mentioned nor even alluded to in any way. Jack is single, and as far as this season is concerned, Cathy never existed. It’s weird.
Cathy was Jack Ryan’s (John Krasinski) love interest in the first season, just as she was in Tom Clancy’s novels. In the books, in fact, Cathy and Jack ended up getting married and having kids and all that — and she’s the First Lady when Jack is elected president. So pretty much everyone figured that Cathy, and thus Cornish as well, would be a mainstay of Amazon’s series.
