Place it at the start of a callout exchange, then follow it with Ceeday Huh if Brian still does not answer, and finish with Oh My God Wow once he finally replies.

This is a short, roughly two-second spoken line in which a voice calls out to Brian and asks whether he can hear them. The direct question lands with an awkward, slightly tense feeling, like catching someone who has gone quiet or lost the connection. It works best as a pointed check-in, not a greeting, because the speaker sounds genuinely unsure whether Brian is still there.
