Albert is only briefly mentioned in this game. However, during a flashback section in chapter 4, we learn about a "kid from G2" that has been bothering Vincent. This "kid from G2" being Albert. Later in the flashback, we see Vincent imitating Albert in a monologue about marine biology. Victor Blake tells Vincent about what Albert will be doing after he graduates, however Vincent tells him that he has "absolutely zero interest in knowing his future career plans."
