  We explore a disc origin for the highly-blueshifted, variable absorption
lines seen in the X-ray spectrum of the Narrow Line Seyfert 1 galaxy
IRAS13224-3809. The blueshift corresponds to a velocity of about 0.25c. Such
features in other Active Galactic Nuclei are often interpreted as UltraFast
Outflows (UFOs). The velocity is of course present in the orbital motions of
the inner disk. The absorption lines in IRAS13224-3809 are best seen when the
flux is low and the reflection component of the disk is strong relative to the
power-law continuum. The spectra are consistent with a model in which the
reflection component passes through a thin, highly-ionized absorbing layer at
the surface of the inner disc, the blue-shifted side of which dominates the
flux due to relativistic aberration (the disc inclination is about 70 deg). No
fast outflow need occur beyond the disc.
