You're Going to Leave Us to Burn?

Bobba Fett leaves two criminals handcuffed to a burning car:

"You're going to leave us to burn?" 
"Rolu?  What's happening?" 

"The owner of the sculpture is probably looking for you.  It may be that he catches you before the fire."

Notes:
Two new verbs for me: arder - to burn, pillar - to catch.  Notice that both are in the subjunctive in these panels.
os, as a direct object, can follow the gerund, resulting in a rare 'double o' spelling: os está buscando or está buscandoos.
