  The flat-spectrum radio quasar B2 1633+382 (4C 38.41) has been monitored for
several years and has presented correlated variability in multiple wavelengths.
In this article, we are performing different analyses for multiple frequencies,
from gamma-rays to radio, as well as, the C IV ${\lambda}$1549 {\AA} emission
line and the ${\lambda}$1350 {\AA} continuum. Using the non-thermal dominance
parameter, we separated the C IV and the continuum light curves for when the
dominant source of continuum is the accretion disk or the jet. We found a
correlation at a delay consistent with zero between the line and the continuum
dominated by disk emission indicating a very small broad-line region (BLR).
From the resulting delay between the 15 GHz and gamma-rays, we estimated the
distance of the gamma-ray emission region from the jet apex to be $\sim$37 pc.
The C IV flux decreases when the continuum and gamma-rays increase at some of
the high activity periods. The C IV profile presents a larger variable
component in its blue wing. The relation between the luminosities of C IV and
the continuum does not completely follow the relation for a quasar sample. Our
results lead us to propose an outflow of BLR material in the jet-flow
direction, a gamma-ray production through magnetic reconnection for the flaring
event of mid-2011, and that there is not enough BLR material close to the radio
core to be easily ionized by the non-thermal continuum.
