We analyze the scattering rate for 2D fermions interacting via soft nematicfluctuations. The ground state is an s-wave superconductor, but other pairingchannels are almost equally attractive. This strongly alters the scatteringrate: At energies beyond the pairing gap $\Delta$, it is renormalized bycontributions from all pairing channels. At energies of order $\Delta$, it isdetermined by the competition between scattering into a gapped continuum anddispersing nematic resonance. The outcome is a "peak-peak-dip-hump" spectrum,similar, but not identical, to the "peak-dip-hump" structure in the cuprates.
