During the conversation about Kraden and Piers communicating by carrier pigeon, Tyrell mentions that he would have no idea where to begin searching for the latter if he had to deliver the message. Kraden's response is classic Deadpan Snarker:
Kraden: Well, it looks like my pigeon has one up on you then, Tyrell. If I can teach it to throw fireballs, maybe you'll be out of a job.
Speaking of snarking to Tyrell, Rief's aside about Sveta shows that he's learned it well:
Yes, Tyrell, this is the part where she just volunteers she's an enemy spy.
