في Human Trials ، شوهد قرب نهاية الحلقة يتحدث مع ابنه والطبيب الذي أنقذ Maya Vie . أخبره الطبيب أن أول تجربة بشرية لهم كانت ناجحة ، لكن دانتي لا يوافق على ذلك لأنه أمرها بعدم القيام بهذا الفعل بعد. بعد أن غادر الطبيب ، أخبره ابنه أن الاختبار الذي أجراه على لنكولن كان ناجحًا.

في Long Into a Abyss ، شوهد وهو يخطو إلى الخارج على الأرض مع Cage. يتردد دانتي في البداية في مشاهدة ابنه وهو يخلع قناع الإشعاع ، لكنه سرعان ما يكتشف أنه ليس مضطرًا لذلك. يستمتع دانتي بوقته في الخارج مع ابنه ويلاحظ الزهرة الصفراء التي يلتقطها. قبل مغادرتهم ، يحاول Cage مرة أخرى إقناع Dante باستخدام The 48 بالقوة للدخول أخيرًا إلى الخارج ، ولكن مرة أخرى يرفض Dante ويعود إلى الداخل. في وقت لاحق شوهد يرسم ، ولكن بمجرد أن يلاحظ أن الزهرة التي التقطها في وقت سابق تحتضر ، يفقد إلهامه ويتوقف عن الرسم.

In Coup de Grâce, he is seen being confronted by Jasper in his office. Jasper takes his sword and threatens to use it on him. Dante astonished asks why he is doing this, and Jasper tells him how two of his friends went missing. Immediately Dante thinks that his son and Dr. Tsing are responsible, and he attempts to find them with Jasper. Dante along with his guards come across Dr. Tsing performing a bone marrow harvesting on Harper McIntyre, with Monty Green watching in terror. Dante frees the two and takes Tsing into custody. However, when he confronts his son Cage, the guards turn on Dante as Cage says that everyone else at Mount Weather wishes to leave. Cage is then named the president and takes Dante into custody.

In Rubicon, he is seen in custody in the quarantine room at Mount Weather. While he is playing a record player listening to music, suddenly Bellamy Blake walks in and acts as a guard. Dante turns up the music to make sure they can't hear their conversation, and Dante asks who he is and what he is doing there. He says that Jasper sent to him to ask figure out how they can save their friends from having a Bone Marrow performed on all of them. Dante tells Bellamy a way to cause a radiation leak, causing the deaths of 11, but allowing the Delinquents to escape. Later, Cage confronts him to let him know that what he has done was pointless, and won't change anything is Cage's plans. He tells Dante that he bombed the grounder allegiance party, with Dante looking in shock. Cage, with what little compassion he has, injects Dante with the bone marrow he needs in order to leave Mount Weather, but still keeps him quarantined.

In Blood Must Have Blood (Part 1), he is still quarantined in his room. Cage walks in to ask for advice, but Dante interrupts him and tells him how disappointing it is to see how much he is messed up in only one week as president. Dante, before Cage walks up tells Cage however that the only way to save their people from the "savages", they must allow the grounders to go, but not the Sky People in order to make sure the threat that faces their people is a small one. When Cage returns to thank him, Dante shows no signs of thankfulness or happiness, only terrified at what he has done to the remaining 100.

In Blood Must Have Blood (Part 2), Dante remains in his room even after the rest of the Mountain Men travel to Level 5 due to a power outage. Clarke, Bellamy and Monty visit Dante for help in saving their friends who are being harvested for their bone marrow without killing everyone. However, Clarke quickly realizes that Dante is not going to help them which he confirms, stating that they cut the power, risking the lives of everyone in the mountain, including the people that helped them. Clarke insists that they are the good guys, stating that they left the turbine intact so that it could be repaired and that they knew Dante's people would be safe on Level 5. Dante simply asks what would've happened to the Mountain Men if they had released everyone and Clarke decides to get into the command center, dragging Dante along to help them whether he likes it or not.

Traveling the empty halls to the command centre, Dante points out that he told them the truth about no one being around and explains that after everything he has done, his people can be free but he can't. Dante explains to Clarke that "deliverance comes at a cost. I bear it so that they don't have to." Bellamy realizes that it was Dante and not Cage who came up with the plan to make a deal with the Grounders which he confirms.

Discovering their friends and family being harvested on the security cameras, Bellamy demands Dante call his people off but he refuses. Clarke instead contacts Carl Emerson and has him give the radio to Cage. Clarke threatens to kill Dante if Cage doesn't let her people go, but Dante simply orders his son to stay the course. Cage refuses to stop with Dante stating that releasing her people would mean the end of his people. Turning her gun on Dante, Clarke begs Cage to not make her kill his father, but Cage reluctantly stays strong, telling Dante that he will take care of their people. Dante tells Clarke that none of them have a choice and both Clarke and Dante affirm that they didn't want this before Clarke shoots Dante in the chest, killing him and holding the radio button down so that Cage can hear it.
