Because you feel trapped IRL and need to escape to as many fantasy worlds as possible? :P 

And I understand, Yes Isa assumed that Luci had found Roxy, but it was an educated assumption. As the howls were not preceded or accompanied yelps or whimpers of pain; nor did Luci growl in frustration, so it seemed likely that Luci believed he'd found their target as opposed to his having found some misfortune. Make sense?
