Subway Crossbow Bolt that fatally struck Grell

The bolt strikes Grell unseen amid the tunnel’s dim glowstrips, drilling between his shoulders. Its lethal precision goes unchallenged long enough for Merdeen to find him, where the wound becomes visible evidence of the regime’s brutality and Merdeen’s complicity.

The crossbow bolt that strikes Grell is never held or discussed directly in this scene, but its presence looms implicitly as the cause of Grell’s death. Merdeen cradles Grell’s wound, the bolt’s fatal trajectory bound into the dying man’s collapse, fueling Merdeen’s guilt and the Doctor’s resolve to interrupt Drathro’s momentum.
