That's right. Go ahead and post your action at your earliest convenience.
I'm kind of hand-waving the troll lifting the ork, mostly because I can't be bothered to look up the rules. If I'm being wildly abusive here, let me know, but even if carrying a person slows your movement speed (and imagine it would), the hero troll should have enough movement to get into the doorway.
Not enough movement to dissappear down the hallway, though. Kynos still has line of sight to the black troll and the ork he's carrying. They're blocking the (possible) target that was shooting at Fenris, though.
