Padon?I didn't quite catch it.I said our guests had come to Dalian the night before....

Padon?I didn't quite catch it.I said our guests had come to Dalian the night before....
Padon?I didn't quite catch it.I said our guests had come to Dalian the night before.为什么用过去完成时呢 不是该用过去时吗
但是这只是对刚才的话的转述,而且后面有明确的过去时间状语,这怎么解释呢

用过去完成时是因为客人已经在我说话之前到大连了.我说话用的是said过去式,客人到大连就应该用过去完成时.
