It's made a point in one of the recent stories (maybe Action Annual?) that Thara got the job through nepotism-by-proxy, as Kara's parents saw her as a replacement. Granted, Thara might think she earned the gig, but there's two sides to every story. I'm not defending Thara here, necessarily; I'm just saying that the insertion of Kara's condemnation seems to work as a balance to the similar attitude of Lois.
