These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Growing the Beard: Sadly averted. The written but unproduced mid-season episode "To The Ends Of The Earth" would have been to Crusade what "Signs And Portents" was to Babylon 5.
Ho Yay: A fair amount of it between Galen and Gideon over the course of the series. Starting with Galen getting himself in trouble with the order for saving Gideon's life in the first place, and, well, this scene in "The Memory of War" sums up the rest:
Galen: Look Matthew, to those of us in my order, another Technomage is the only family have. After I was asked to leave the order as a penalty for having too much contact with the outside, I came to rely on you.
Back when this actually aired on TV, this troper showed a Galen/Gideon scene to a friend who was not familiar with the show, was not into slash or familiar with shipping. I asked if I was imagining the Ho Yay. His response was unequivocal: "It's not your imagination!"
