1) Use were instead was because the verb wish dictates the use of the conditional. [1pt.]
2) Use whom because it occupies the object position within the relative clause "whom he was interested in" ("he" is the subject.). [Note: you could write this as "in whom he was interested" also] [1pt.]
3) Remove the comma after him. The and is connecting two verbs here; therefore it is not needed. [1 pt.]
Total = 3 pts.
