OK, so I stopped watching Chase the second or third time that the tiny Kelli Giddish, playing U. S. Marshall Annie Frost — if ever a character name said “ice queen,” that’s the one  — physically subdued some hulking villain mostly, it would appear, through what I’ve taken to calling  “the power of her blondness.” At least over on the now-defunct Good Guys, Bradley Whitford didn’t take this TV-heroic stuff so grimly seriously. Plus, you got to see longer scenes with North Texas locations.

But now comes word that Dallas actor Steven Walters — currently commanding the stage in Second Thought Theatre’s Thom Pain (based on nothing) — will be playing a recurring character, a computer nerd-type.  He’s the guy, as Walters describes him, who’s always seen lit by the glow of a computer monitor while he pretends to type frantically. Tonight starts the two-part story.
