除了回聲，echo的其他意思你知道嗎？

This brings me to the one note of disappointment I must echo from our Benefactors. Obviously I am not on the ground to closely command or second-guess the dedicated forces of the Overwatch, but this does not mean I can shirk responsibility for recent lapses and even outright failures on their part.

——Half-Life 2

這讓我想起保護者要我傳達的事情，這令人非常失望。當然我並沒有立場直接指揮，或者介入監管隊的微妙組織。但這並不代表我能推卸所有的責任，無論是監管隊近來的疏失……甚至是失敗。

——《半條命2》
