Kellen did feel like he was walking up to a tv set or a movie set given how many traps he was seeing. It felt less like an actual Guild building, and more like someone should be filming this and putting it on t.v.
The Healers were in their glee, quite excited to chat and explain about what each trap did and how it would harm the bad guys who approached the traps. It really made Kellen think that the obsession that this one Healer had was traps, and from the gleam in Brent's eyes, that appeared to be what he thought as well.
Kellen was glad that Brent was amused, even as Sergei and Kellen remained on high alert. Partially because Kellen could tell that the further they went in that something wasn't quite right and it was probably related to the Espers going a little too far in their desire to protect everyone, and also because it was so quiet.
