The multiplicity of massive stars is higher than that of their
lower-mass cluster siblings, and the dense environments in which they
are found suggests that interactions with neighboring stars impacts
their formation. Disk-assisted capture has been shown to be
insignificant for solar-mass stars; we present the results of studies
suggesting that for massive stars, capture during the protostellar
phase is a mechanism that cannot be ignored. We note that the Cep A
HW2 region may show signs of interactions leading to a captured
binary.
