  The orientations of brightest cluster galaxies (BCGs) and their host clusters
tend to be aligned, but the mechanism driving this is not clear. To probe the
role of cluster mergers in this process, we quantify alignments of 38 BCGs in
22 clusters undergoing major mergers (up to $\sim 1$ Gyr after first
pericenter). We find alignments entirely consistent with those of clusters in
general. This suggests that alignments are robust against major cluster
mergers. If, conversely, major cluster mergers actually help orient the BCG,
such a process is acting quickly because the orientation is in place within
$\sim 1$ Gyr after first pericenter.
