Great episode.
But for the reviewer stylenjess - " I'm like 99% sure there is no way for a coach to cross the English Channel."
You are 99% wrong. There are ferries across the Channel and a tunnel under it. Since we didn't see any scenes on a ferry, it's more likely that they used the Channel Tunnel. There are trains that carry cars, lorries and coaches through the tunnel. And it's quite normal for a coach trip between the UK and France to be on the same coach throughout.
