The sitting-in-front-of-the-computer-thighs bit is really weird
There was another gag about that in an early issue of Batgirl, I believe. A telepath has just rewired Cass's brain to accept speech and Babs is testing it with word association. After "window," she tries a harder word, "cellulose." After a moment's thought, Cass points to Barbara's thighs. Babs protested a bit.
