While the publication of the first detected brown dwarf and exoplanet were released in the same year, the populations have largely been examined independent of one another. However, over the past six years, or since the Cool Stars 16 meeting in Seattle, the field of comparative brown dwarf/exoplanet studies has rapidly advanced. The discovery and detailed analyses of several directly imaged exoplanets in the effective temperature regime of L and T dwarfs (e.g. HR 8799bcde, 2M1207b, Beta Pictoris b, 51 Eri b), and isolated young brown dwarfs in the same moving groups as giant exoplanets (e.g. 2M0355, PSO 318, W0047, SDSS1110) have revealed strong connections in the features of the two populations. Anomalous observables such as extremely red infrared colors, "under-brightness" in infrared bands (discovered through astrometric studies), and gravity shaped spectra of young low-temperature sources, have emerged in studies of both populations. Perhaps the most exciting connection is that of several isolated, young, brown dwarf candidates with estimated masses below the classic "deuterium burning" limit traditionally used to differentiate between the two populations. These sources introduce a new puzzle in our idea of how planets and low-mass brown dwarfs may form. The timing of the Cool Stars 19 meeting is excellent for bringing together leading researchers in studies of directly imaged exoplanets and isolated brown dwarfs. There are monthly (even weekly) discoveries being reported of crossover sources that would benefit from a summary of how to use the two populations in concert. We propose a splinter session that will review the overlap within current data from instruments such as GPI, SPHERE, and MagAO and prepare for what we might obtain with next generation instruments such as JWST.
