Angrod visibly pauses a moment, then continues moving forward. As he does so, the elf raises his right hand and, in a manner like a conductor, first flags the passage to the right and then the continuing passage forward.
The elf sneaks forward, keeping his eyes trained ahead, then stops for a moment, with a signal back to the others, and he pauses in front of the passage right.
[sblock=OOC]That seemed rather awkward to describe. Feel free to just make any interpretation necessary to make better sense of it.
Still hiding and moving silently (do you mind if I use "sneaking" as shorthand?). Trying to "spot" forward and then to the right (explicitly using an action to make a spot check down the right).[/sblock]
