A late night co-op call turned into something else

Was just playing a normal session with him online, nothing planned, and then he yawned into the mic near the end and the whole tone of the conversation shifted a little. Small moment but it stuck with me — the confident, teasing voice from the setup dropped into something quieter and more genuine for a few lines before picking back up. That kind of tonal shift on a small trigger is exactly the sort of thing that makes an online-friend character feel less scripted.
