Honestly surprised that HSR isn't more involved in this season, from both teams too
If you really want to travel fast through west Taiwan, HSR is the way to go, although not every station has a connecting railway like Taipei, I feel like using the buses, metro or rental bikes would still be faster than going on the regular ones, if I was in the game, I will fortify the line with 5 chips on every station asap, and I think Sam is overhated this season, but they've really should've shoot straight down Kaohsiung and take Badam's stations while they're still stuck in the east.
Either way though, I've been enjoying this episode, this one probably swings from "we're so over" to "we're so back" for both teams, although maybe I'm biased because I'm Taiwanese, I'm really glad that all of them enjoyed Taiwan and I hope they'll still come here in the future, thanks, Jet Lag Team.
