My general idea is the trope of like DB not being used to fighting in a team and like overextending himself causing Týfurkh to get captured, and like the rescue being the completion to that mini-arc or something for like advancing some rp. Alternatively the three get swarmed and like Týfurkh who's busy with the magic is like captured and the other two are unable to get him back from the swarm. To be honest it's quite sketchy in my mind and needs more details.
