It appears that originally the player could recruit Thane, Tali, Samara or Legion a lot earlier in the game; possibly directly after the prologue like Miranda and Jacob. By using an editor tool to unlock them from the beginning of the game, players will discover that the four have extensive dialogue for virtually every mission in the game, including missions which must be complete before their official recruitment missions. Furthermore, there are some unique scenes should the player bring Legion in particular along onto certain missions, such as characters commenting on his presence.

Legion's presence also triggers an exclusive Paragon Interrupt during Tali's recruitment mission. Upon meeting Tali, she will notice Legion and immediately draw her gun, triggering a Paragon Interrupt prompt. If the player doesn't press it, she will open fire at Legion who will run for cover.
