Head below the break to see the news about the episode! Not super spoilery, only the title, but just playing it safe with the break.
If you head over the source below, and click the "NEW EPISODES! THURSDAYS AT 6:30/5:30C" drop down, it looks as though episode 73 is titled 'Too Far'. That's interesting, considering that was not one of the 26 titles previously revealed.
