Linda James thought that her son-in-law would definitely deal with her after she told him the truth. After all, she had exposed his greatest secret to Melanie Taylor. 'Melanie Taylor and Finn are basically mortal enemies. It's obvious that Finn will punish me for telling the former about his weakness. The two are basically mortal enemies, and doing that meant that I've sided with his enemy. It would only be wise to get rid of me while he still has the chance.'
To be honest, Finn Taylor desperately wanted to do so. However, kinship still mattered to him.
Finn Taylor liked Yvette Larson, and Linda James was the latter's mother. This meant that the former couldn't possibly treat the older woman simply as his enemy.
