Boggs

Boggs is first introduced as President Coin's right hand man until Katniss offers to assume the role of the Mockingjay. It then becomes his job to keep her alive.

Job
Boggs becomes Katniss's protector. While in District 8, as the bombs are being dropped, he covers Katniss with his own body so that she will live, demonstrating this. By showing her that he is not utterly devoted to Coin, he begins to gain Katniss's respect and trust. When President Coin sends Peeta to join Star Squad in the hopes that he will kill Katniss, Boggs swears that he will keep her safe. He has a heated conversation with President Coin on the subject, showing that his loyalties are with Katniss rather than Coin.

Mockingjay
Boggs was working as President Coin's right hand man and was like a puppet to her Katniss notes. When Katniss fled the room because of Peeta's interview Boggs tried to stop her but Gale got in his way and accidently gave Gale a bloody nose. Boggs was assigned to guard Katniss while she films propoganda. Boggs and the group go to District 8 for their first shoot.

When they arrive at District 8, they go to one of the hospitals and decide to comfort some of the patients. Boggs keeps a close eye on Katniss and makes sure nothing happens to her. After their run-in with Finnick in his underwear, Katniss decides to go ahead and like Boggs. When the Capitol attacks the hospital, Boggs is ready to go into combat, but holds back Plutarch so Katniss can fight their enemies. Boggs makes sure they are filming as they battle and watches Katniss to make sure she is safe. When the attack is over and Katniss makes a brief speech, Boggs tells them that they have finished filming the propo and they return to District 13 to receive medical treatment. The group meets in the command room and discusses the complete propo. After they finish, they decide to allow Katniss go back in combat and shoot more propos when she is fully recovered. Boggs talks with the head of the rebellion to discuss more topics and objectives they must deal with.

Boggs assists the head of the rebellion in evacuating the entire district to safe bunkers after Peeta warns them of the bombing on District 13 by the Capitol. Boggs, Katniss, Gale and the others resurface to the heavy damaged remains to shoot more propogandas but Katniss and Finnick break down because they can not take it anymore. Boggs and President Coin form a rescue team that he will lead to save Peeta, Johanna, Enobaria, and Annie from the Capitol. Boggs knocks Peeta out after he tried to strangle Katniss. He goes with them to District 2 and enters The Nut with them to meet Lyme. The group argue over the idea of bombing The Nut filled with people. Boggs gives them the choice of blowing them up or giving them a chance of escape. He updates them of Peeta's condition after they retreat to the Justice Building.

Boggs goes with the sharpshooters squad to the Capitol and is leader of the group. The group train and film for the propoganda. When a member dies, Peeta is sent as a replacement. Katniss speaks with him about the replacement and Boggs points out Katniss will be a big vote for who will be the new leader of Panem.

Death
Boggs meets an unfortunate death. As the Star Squad is clearing a street of pods, Boggs accidentally steps back onto a tile and has his legs blown off by a mine pod. Within a building, as they shelter from the effects of yet another pod, Boggs transfers the Holo over to Katniss's control. He also warns her not to trust "them", encourages her to continue on her mission to assassinate Snow, and tells her to kill Peeta (although Katniss never finds out what he is referring to as not trusting "them", and why she must kill Peeta.). Boggs dies from loss of blood, and his corpse is left behind when the Star Squad moves on.
