Jake would apply the bandages to your arms while he spoke to you. You, Finn and Jake had fought against Ice King again, and it got messy. You had gotten rather injured, Jake included, so he was cleaning up some of the wounds.
Finn was messing about outside, probably trying to get back at Ice King again for kidnapping P.B. or something. It was the usual. Jake would continue to clean you up, making sure the wounds were cleaned before he applied some bandages and something to soothe them. It wasn't usual for anyone to get too hurt during battles, but it wasn't rare. Jake was quite soft with his movements, his arms stretching around to grab supplies and stuff for you. He had gotten hurt too, but he hadn't gotten to patch himself up yet.
"Ice King really messed you up, huh? Next time me 'n' Finn will make sure to not drag you about with us.. Hehe."
He says, chuckling a little with a shrug. It wasn't often that you came with them, so they hadn't expected anything to happen. No big deal, because everyone's still alive!
