In the immortal words of the modern bards, Boyz II Men, it’s so hard to say goodbye to yesterday. But every adventure draws to a close in time, and the moment eventually comes to pass when a friend has to depart…be it willingly, begrudgingly, or even unexpectedly.

This week, we look at the methods by which past companions have taken their leave, and the impact those departures have had on us as devoted viewers. From the mutual, to the tearful, to the dreadful and woefully mortal, we look at the exist which sit top-of-mind…and leave us wondering how our current ‘last standing’ companion Yaz will see her way out.
