Albert was never a suspicious person, at least not in his past life, which perhaps had something to do with his former living environment. But now, he had to admit that Professor Rowena Smith was somewhat suspicious—at least based on the connections drawn from the various intelligence he had gathered so far.
Undeniably, this judgment was somewhat colored by Albert's own bias as a transmigrator, but he still believed that until Voldemort was completely done for, every wizard who came to Hogwarts to serve as the Defense Against the Dark Arts professor was likely up to no good, and might even be entangled in certain affairs.
Perhaps the ultimate answer would turn out to be vastly different from his speculations, but until Professor Smith left Hogwarts, there was no harm in Albert temporarily placing him on his blacklist.
