Lachlan Jimenez's words were also meant to exonerate Oliver Watson and the other two Palace Masters.
During the earlier search at Sky-scraping Mansion's premises, he was the only one who purposely sought out Peace Adams' sidekick, wanting to drag them out.
Oliver Watson and the other two even advised him against it, saying that if he couldn't find them, it didn't matter—a trivial sidekick surely wouldn't know about that Devil Path technique.
Thus, as soon as Lachlan Jimenez finished speaking, Oliver Watson, the Earth Palace Master, and the Mystic Palace Master all looked at him gratefully.
Since Peace Adams' sidekick wasn't within the Sky-scraping Mansion premises, then it couldn't be said that they escaped under their noses, making them blameless.
"Since he isn't at the Sky-scraping Mansion premises, he certainly knows nothing about what's happening here! In that case, let's find him ourselves... kill him, to eliminate any future problems!"
