"Don't say I didn't warn you." He doesn't want Rezo to stay in the same tiny room as him, but while Zelgadis is furious with Rezo, and more than a bit afraid of him, he also still considers him family. Look, Zelgadis is a complicated man with complicated feelings. If Rezo wants to take stupid risks, he's an adult and now he knows the risks.
