I've been caught up on the fact that The Crow is only bound to Spider because he attached a bomb to Glint.
I guess I have to preface this topic with a question; where do Ghosts go when they disappear? When your Ghost isn't visible, yet still communicating with you, is it in a pocket dimension? In your head? Back at the ship?
That being said, assuming Glint isn't a physical entity when he disappears, why not just... leave without coming out? Could Glint explode as a nonphysical entity? If so, what positive emotion do you feel at the thought of Uldren becoming a firework?
