Finn and Jake quarrel leading Finn to take on the dungeon by himself to prove that he can handle it. He is confronted by the demon cat and beaten up. A angel picks him up and he is told that he will be saved by this "guardian angel" which he believes since she healed him upon lifting him into her arms. He expected to be saved by her. After being plopped into a stew (meeting up with Jake again) HE RELIES ON THEIR TEAMWORK TO BE SAVED AND REACH THE END NOT JUST JAKE BOTH OF THEM TOGETHER. Then they are actually saved by Princess Bubblegum when being attacked by burning eyeballs.
Well, this one's certainly a bit tricky. I mean, at first he thought his bravery and mitts would save him, but it wound up inadvertantly being Jake... Then there was the so-called Guardian Angel coming to save him, but Jake sort of saved him from that thing... And then he thought Jake would help him break out of there, but it wound up being Princess Bubblegum and her ridiculous laser-swan... It's a bit ambiguous.
I'll put my guess down for the false Guardian Angel first, followed by Princess Bubblegum and her swan for the true rescue.
fin wanted to prove a point abut how he can do stuff by himself but then gets captured and put in a cage jake shows u there and trys to save him but that goes bad and princess bubblegum ends up saving them bolth =]
