In the second episode of season one, Merle had shot off his gun on the roof. People around the area had no idea they were filming and were scared Michael Rooker was an attacker. The police and SWAT team were called in.
Luckily the situation was explained and no one was arrested.
Glen Mazzara stated “‘Triggerfinger’ took place within a day of the Barn-mageddon, as we call it. Daryl is rocked by that. He wanted to be Carol’s knight in shining armor and take up this quest and be the one to find that girl. He now questions his self-worth. Was he a fool to ever take on that quest? This brings up issues of his upbringing. He actually is going to hit Carol and pulls back his fist because that is his learned behavior and her learned behavior is to take it. Her generous spirit is willing to take that because she cares about him so deeply.”
"It’s important to note that Shane was Rick’s best friend. So no matter how much Rick knew, he didn’t want to admit to himself that he knew. It wasn’t until that walk out into the woods, when Shane was leading him to his death, that he really accepted the fact that, Wow, this guy is not the guy I knew any more." -Robert Kirkman
The name of the episode, “Cherokee Rose,” refers to the fact that Daryl found a Cherokee Rose, which he believes is proof that the group will find Sophia.
" When the Trail of Tears started in 1838, the mothers of the Cherokee were grieving and crying so much, they were unable to help their children survive the journey. The elders prayed for a sign that would lift the mother’s spirits to give them strength. The next day a beautiful rose began to grow where each of the mother’s tears fell. The rose is white for their tears; a gold center represents the gold taken from Cherokee lands, and seven leaves on each stem for the seven Cherokee clans.”
In a previous episode, Milton had demonstrated to Merle and the others that duct tape was effective in protecting against walker bites. Ironically, Glenn’s life was saved by the duct tape that had bound his forearms to the chair - when the walker tries to bite him, Glenn jams his forearm in the walker’s mouth before driving the wood stake through its head and killing it.
