Gerard, now a resident of the clinic's gardens, reminds Jamie to shout for his mother, who rescues him. Vasco gives up after Dave attacks him, and Alex threatens him with a shotgun. The next day the judge rules in Alex's favor and rejects the precedents as attempts to abolish normal human feelings by decree, a violation of the Thirteenth Amendment to the United States Constitution, which forbids slavery. The ruling will likely to hamper research in the long run, and prevent patients from selling their tissues rather than donating them for research.
