And yet, in regards to romance, every other character doesn't seem to give a rat's ass about the player's gender, race, past history, and so forth, but suddenly when it comes to Eder then it's "Oh but he can't feel that way due to something totally irrelevant".
To me it just seems like they didn't want to give in to the fans even when what they were going to "give in to" made complete sense and fit in perfectly.
And even if Eder found the Watcher's identity and lifestyle so abhorrent, he still will voluntarily spend months of his own life in the Watcher's close company, day and night, and not even for personal gain (such as when the Watcher is comatose). So that has not deterred him.
