Within the data for Chapter 2 are an unused series of voice grunts; the filenames for them are all "Snd_txtrx" followed by a number. This name deciphers as "Sound Text Rx," implying that these files were intended for Rouxls Kaard, who during regular gameplay is one of the only characters to feature dialogue portraits but no voice grunts (instead using the generic text scrolling sound).
