One thing to keep in mind is that these episodes are shown out of order. This past episode was actually
both the second episode filmed for the season and the second episode aired, but that's a coincidence. The first episode aired was the tenth episode filmed, and actually the special episode aired in February was the sixth episode filmed for
this season.
Based on what we've seen in episode 206, 210 and 202 (in that order) I suspect that they realized early on in filming Season 2 that they made things too rough, and toned things down a bit.
Next week's episodes (there are two) are 214 and 205, and then the week after is 216. You can monitor how they're ordering them here:
