In Backlash, Ben starts to go off on an Inner Monologue about how Jacen, the Nightsisters, and the Sith only value their own needs, only to have Vestara interrupt him mid-thought to offer him water and exchange snark.
Han Solo gains a flamethrower to use against the sparkflies in Backlash. To say that he has fun with it would be an understatement.
In the Jedi Academy Trilogy, Han was briefly imprisoned in the spice-mines of Kessel, where he had a near-lethal encounter with the energy spiders that make the spice (as webbing). After he escaped, Lando bought out the spice-mining operation. In Fate of the Jedi: Outcast, Lando mentions he's been trying to expand, but is having difficulties...
Lando: Efforts to transplant colonies of the energy spiders that produce the stuff haven't been very successful. Han: You're trying to get them to survive on other planets?! Lando: Yes, but they just stop feeding and dieó Han: Good!
