If "Such Sweet Sorrow, Part 1" had you wondering what wild networking skills led to Tilly meeting a queen, we regret to inform you that you've definitely missed a 'Short Trek.' "Runaway," the mini episode where Po, the queen of Xahea, and Tilly meet for the first time, is available to stream. But, since you're already here, let Mary Wiseman catch you up real quick before Po and Tilly return in "Such Sweet Sorrow, Part 2." Star Trek: Discovery streams exclusively on CBS All Access in the United States and is distributed concurrently by CBS Studios International on Netflix in 188 countries and in Canada on Bell Media’s Space Channel and OTT service Crave.
