have exhibited indirect evidence for slower outflows in the form of blueshifted optical/UV emission and absorption lines [@Roth2018; @Hung2019; @Blanchard2017], suggesting that outflows may be common. This is crucial, as the expanding material offers a promising means to form the apparently ubiquitous reprocessing layer required by the optical/X-ray ratios. Suggested models include an Eddington envelope [@Loeb1997], possibly inflated by radiatively inefficient accretion or an optically thick disk wind [@Metzger2016; @Dai2018]; or a collision-induced outflow [@Lu2020].

Understanding whether the optical reprocessing layer is connected to the non-relativistic outflows seen in some radio TDEs is therefore a crucial, and as yet under-explored, step towards a pan-chromatic picture of TDEs. Acquiring early observations in the optical, X-ray, and radio bands can allow us to distinguish whether outflows are launched *by* accretion, or *before* accretion (i.e., in the collisions that ultimately enable disk formation).

In this paper, we present a detailed study of the UV, optical and X-ray emission from AT2019qiz: the closest TDE discovered to date, and the first optical TDE at $z<0.02$ that has been detected in the radio. We place a particular focus on the spectroscopic evolution, finding clear evidence of an outflow launched well before the light curve maximum. By
