I just realized that the whip may be more evidence that Tarquin's a warblade.

Somebody's probably brought this up already, but don't warblades get an ability that let's them switch weapon specific feats like Weapon Focus from one weapon to another, provided that they practice with the weapon that they're switching to? He certainly seems comfortable with switching weapons, and thus tactics, at least more so than Roy was when his greatsword got busted. He spent most of a strip looking for another two-handed weapon, after all.
