Tobias was never homosexual, so there's no point in discussing it any further, but I have a feeling that Tobias definitely would've been suicidal had he not had the chance to trap himself as a hawk. I always took the trapping itself as a play on that topic, as a means for Tobias to escape his life, and I saw nothing accidental about it even though Tobias claimed it to be so. The lines from the Ellimist in #13 more or less confirm this, imo.
