Glover believes Lionel has two competing agendas with Lex—for Lex to become his own man and for Lex to follow in his father's steps. This becomes frustrating for Lex because Lionel wants his son to be both "loyal follower" and the "best person he can be". This all plays into Lionel's "pretty huge ego". John Glover believes if Lionel and Lex were not related Lionel would have "destroyed" Lex early on because he views his son as "weak". Lionel is also bound by the fact that Lex is his heir, although he does not trust Lex. Lionel's distrust of Lex partially arises because he believes Lex is a coward. John Glover said, "It's not that is meant to be a foe; it's just that the poor boy's weak, so must mold him. Lionel is continually trying to strengthen his son, to teach him. is just a hard student."
