Leonard: You shush, I'm happy. I want to talk about it.

你别出声我乐死了我想谈谈。

youdao

Shush! Here he comes. I'll talk to you later.

嘘！他来了。我一会儿再跟你说。

《柯林斯英汉双解大词典》

And when he shushed her (" Always be silent when searching out your target - lest they find you before you find them "), she would shush him right back, which told him she was paying attention.

而每当他发出“嘘”声使她安静下来时(“在搜索目标时一定保持安静——避免在你发现他们前就被人找到”)，她都会马上“嘘”回一声，这是告诉他自己正留着神呢。
