Well. He'd started to depart, but as he'd started to head off, thankfully he'd spotted the movement. A movement he failed initially to identify.
So he turned, looked to the Breen and cocked his head. His version, being someone who just signed and was non-verbal, of a softly issued 'Huh?'. Issued as he watched the two people. Signed. "I didn't quite catch what my friend said." The deaf man started to say then, the choice plumped upon to sign friend. A lie but he hoped the Q who happened to be playing a role, would well. Buy that.
Elements, he hoped this Breen happened to know sign. It'd be awkward if they didn't as well, the mask thing happened to mean they were someone he'd never have managed to lipread! "But, we're here investigating a murder that occurred recently, if you're able to let-" He remembered the wave, decided he'd not be going to the holoarcade then, or so that non-verbal request seemed to make it. "-I and my friend in to look around, we'll do our best to be out of your hair as the humans say it, as quickly as we can."
When someone else turned up, Elohae initially twitched in surprise! He'd failed to notice them as they approached, a fact he quickly recovered from then. "Hello, do you know sign?" He rapidly signed then to Khal before he internally kicked himself, having realised he didn't know if this Q happened to know sign either!
He hoped so, or he'd not be much help. Well, until he pulled his PADD out. He'd do that if he needed though, it wasn't something that phased him much. Elements though. Part of him, in the face of all this, really wanted to do some research into those visor things he'd encountered once or twice. They seemed rather useful.
