'Alone' served to expose Bob's backstory every bit as much as it acted to flesh out Sasha's ( Sonequa Martin-Green) personality more. Not suspect at all, right? Tonight's theme of being alone was established by Bob's story, and then carried along strongly for the rest of the hour. We learned (or, possibly, were merely reminded) that Bob's former two groups of survivors all ended up dead, with only him surviving.
Tonight's cold open introduced viewers to Bob before meeting up with Rick's gang during the occupation of the prison. What about Bob? Bob Stookey ( Lawrence Gilliard Jr.) has been one of the strangest characters on The Walking Dead , mostly because we know very little about him aside from his medical training and battle with alcoholism.
