Improprietous? I don't think that's a word, your Honor!
The two times Howlett and Yuli formed Quetzal occurred near the end of "Holiday," our 9th storyline and in Act III of "A Long, Long Trail A-Winding," the 24th storyline. And while I don't want anyone to think I engineered this entire storyline just so Howlett and Toch could finally exchange a bit of adversarial prose, well, I'm not one to look a gift scene in the mouth, am I?
