Three acts, three missions, three shocking revelations: Is “Triangulation” Coatl’s masterpiece episode? Scott sure seems to think so, citing everything from the amazing long take atop the volcano rim to the deceptively simple, almost unbearably tense conversation between Trevor and Ablah that caps the episode. Tom, for his part, argues that the idiotic “Battle of Seven Dunks” fatally undermines everything else. One thing is for sure: with this episode, clocking in at nearly two hours and bringing in a whole raft of characters both old and new, Coatl Season 2 has decidedly upped the ante.
