Swinging leads on Tennis Shoe, my partner dropped a carabiner of nuts from the top pitch, and its landing was not observed. We climb with a double set of nuts, and so we were still sufficiently equipped after this error, that we continued up Lazarus to extend the climb. During this climb, I slipped off while seconding, and minorly strained one ankle which slowed me down a little for the rest of the day. Having gotten back down to our packs with plenty of daylight, and wishing to attempt to retrieve the dropped gear, we also climbed Heather Wall as it would place us at the top of Tennis shoe, from where we could abseil to look for the carabiner of nuts. It was a very slow climb, even for us. Finishing this, we set up the abseil and began our search on the grassy ledges below (the rope was threaded around the tennis shoe boulder, and backed up by nuts on the wall behind). I abseiled, with my partner waiting at the top so as to clean the anchor after I was off the rope. I was unable to locate the dropped gear, and my partner then had a *great* deal of trouble with freeing the rope, spending what felt like an eternity trying. By this point it was getting late in the day, and so I returned to our packs below Heather Wall to retrieve warm jackets and headtorches, and make my way up the 'usual descent' route to assist. While I was doing so, the rope was freed and dropped. As the light was fading, my partner felt uncomfortable with attempting to find their own way off so, I continued up around the descent route to find them, eventually needing the headlamp. I found my partner quite shaken up, a bit cold and lonely, and very glad to see me. We made our way back down to our packs and out to the car by around midnight and home without further ado.
