Filip and Fitz attempt to fully upgrade the Hacker News app, and address the runtime bug they saw at the end of the previous episode. This adventure takes them to fun places, such as the internal implementation of string interpolation in Dart SDK, and at one point they even have to resort to print debugging.

Will they figure it out? Watch to find out! (Yes, they will.)
