When Buckley makes a "web call" to the Eppes family, he claims he's in Liechtenstein, but the background of skiers is clearly a video loop, visibly cross-fading on each iteration. Even if it is intended to be a ruse by Buckley, the Eppes family should have spotted it immediately and called him on it.
At the end of the episode Buckley makes a video call supposedly from Lichtenstein it appears to be early evening in California. However it is clearly daytime wherever Buckley is, and Lichtenstein is 9hrs ahead of California, which would make it the early hours of the morning in Lichtenstein, and indeed throughout the whole of Europe.
