The assurance that company provides can only last so long, because Blue's stamina doesn't last, and he has to relent by the time there's a place to sit. He can't ask Yuri to idle at his side for however long it may take to recover, either, so the Mu insists he carry on with what exploration he means to get up to himself.

Even once the man's receded into the crowd of peculiar people and structures, Blue can still glean sense of him, as such a distinct connection has been made. It's like a soft beacon of light he can perceive with his eyes closed, and knowing there's no spike or sudden change in its state means there's less to fear for now.

Perhaps they'll meet again.
