Tim

Tim was a former bandit. He was a secondary character in Season 1 and 2. After spending a few months stealing and killing with his friends, they choose to attack the school, resulting in the death of the others and his capture. Tim was eventually released as the others recognised that he did not fit in with the others. He soon became a valued member of the group.

Pre-Apocalypse
A few years before the end of the world, Tim's mother died in a car crash, leaving him living his life "on autopilot." At high-school, he claims to have been in the same year as Sam Cooper, but they apparently never communicated. At some point, he became friends with Logan and Tony, with whom he survived the initial outbreak.

"A Safe Place"
Tim is one of the bandits that try to steal from the school. He is the only member, however, who survives and is captured by Frank.

"Trouble Afoot"
Tim is tied up in one of the abandoned classrooms, Cain tries to torture him to try to get information about his group from him, but he insists that they were the only ones.

"What You Have To Do"
Tim's torture becomes more brutal as Cain takes control of the group. He is shown to be barely conscious after a vicious beating.

"What We Are"
After Cain is imprisoned with Tim, he stays mostly silent, only asking for water when Blake asks if he needs anything. When he is asleep, Cain escapes.

"What We Become"
When the group is looking for Cain and Maeve, Blake gives Chloe the choice of what to do with Tim. She asks him bluntly if she should kill him or not, to which Tim says he doesn't know. He tells her about the things the other bandits did after the end of the world and that even though he never partook, he still let them do it. Chloe then leaves and presumably lets him go, as the two are later seen at the gates when Blake, Joely, and Maeve return.

"Are We Okay?"
Tim, Blake, Charlie, and Maeve go on a run to look for food. While looking around, he remarks to Charlie that he missed bread and how soft it was. When Charlie simply says "ham sandwich", he clutches his stomach and groans. When the group then hears an alarm ringing from the nearest fire-station, they investigate and discover the members of Bryce's Group. With Dexter injured, they take them back to the school. Later, Tim supports the idea of trading with the others, stating that they "need the food." The next morning, he mentions that he knows Sam from high-school, but does not dare talk to her, saying that he doesn't "even recognise [him]self". Claire then reassures him, telling him he is "one of us, now."

"What Have You Done?"
When Sam takes down some infected on the other side of the fence, Tim joins her and offers her water. The two then talk to each other for a while, with Sam confessing that she recognises him from school, mentioning that he "started hanging out with these two older guys and then just disappeared." This makes Tim grow quiet and he tells her that they're "both gone."

"Gone Too Long"
Early the next morning, Tim is revealed to have slept with Sam. Later, when Scavs attack the school, he defends the others by killing Wainwright, slicing his throat open with a machete.

"Unstoppable Force"
After some friendly talking with the others at the school, Tim accompanies Blake on his search for Trevor. When they are attacked by Scavs, Porter shoots Tim in the throat, leading to him bleeding out while Joely tries to save him.

Blake
As with the other members of the School Group, Blake and Tim's relationship was strained at first, owing to his association with Logan and the other Bandits. Over the six month time gap, however, Blake appears to have begun to trust Tim and they seem friendly to one another.

Cain
Cain was never sympathetic to Tim following his capture, beating him for seemingly no reason as his mental state deteriorated.

Claire
Though Claire is—like the rest of he group—distrusting of Tim at first, she did not wish to have him killed. Eventually, she begins considering him as one of the group, as she reassures him that his past indiscretions don't define him now.

Charlie
Tim and Charlie do not interact much at first, they appear to have formed a healthy relationship over the six month gap. They are shown joking around with each other on a run.

Sam
Tim and Sam both went to school together, though their relationship during this period is not known fully. When they reunite during the apocalypse, where they discuss their past and eventually sleep together.
