  Sympathetic eruptions of solar prominences have been studied for decades,
however, it is usually difficult to identify their causal links. Here we
present two failed prominence eruptions on 26 October 2022 and explore their
connections. Using stereoscopic observations, the south prominence (PRO-S)
erupts with untwisting motions, flare ribbons occur underneath, and new
connections are formed during the eruption. The north prominence (PRO-N) rises
up along with PRO-S, and its upper part disappears due to catastrophic mass
draining along an elongated structure after PRO-S failed eruption. We suggest
that the eruption of PRO-S initiates due to a kink instability, further rises
up, and fails to erupt due to reconnection with surrounding fields. The
elongated structure connecting PRO-N overlies PRO-S, which causes the rising up
of PRO-N along with PRO-S and mass drainage after PRO-S eruption. This study
suggests that a prominence may end its life through mass drainage forced by an
eruption underneath.
