1978 was a common year starting on a Saturday.
Tuesday 31 January: A trap goes off at the executive training school, intended by Dr. Marcus to prevent spies from discovering his t-Virus research. He suspects the spy was sent by Dr. Oswell E. Spencer.
Friday 3 February: Dr. Marcus begins research on annelids, and infects four leeches with his new t-Virus strain. He notes his belief that their single-minded biology is perfect for bio-weapons research.
Friday 10 February: Dr. Marcus notes that the leeches have doubled in size and there are now eight, but due to a lack of suitable nourishment they turn to cannibalism and two are killed.
Saturday 11 February: Dr. Marcus finds signs of an unauthorised entry into his lab. He considers having Drs. Albert Wesker and William Birkin assist him in finding the spies.
Tuesday 7 March: In an attempt by Dr. Marcus to feed living animals to his leech test subjects, half of the leeches are killed. On a positive side, he notes their cannibalism has ceased and they are developing a collective thinking.
Saturday 22 April: Dr. Marcus notes his leech test subjects have fully developed a collective mentality and now move, behave and attack as if a single being.
Sunday 30 April: A staff member at the laboratory discovers Dr. Marcus' research, and he begins to consider the use of humans as a food source.
Saturday 29 July: Umbrella HQ has the executive training school shut down, but Dr. Marcus continues to perform his research in its laboratory. Executive candidates Dr. Albert Wesker and Dr. William Birkin are assigned to the Arklay Laboratory as chief researchers.
Monday 31 July: Drs. Birkin and Wesker arrive at the Arklay Laboratory by helicopter. Dr. Birkin learns of Dr. Oswell E. Spencer's own side of the t-Virus Project, which kills the infected rapidly, making it an unsuitable bio-weapon. Aware the laboratory is performing bio-weapons research on the Ebola Virus, he begins to develop a new t-Virus strain with Ebola genes spliced in, and soon creates a contagious virus that mutates the host to survive in a murderously aggressive and mentally-deficient state, making it a more dangerous military weapon. During their tour of the laboratory, the two researchers also meet the twenty-five year old Lisa Trevor, an Umbrella test subject kept in the lab for over a decade.
