From that point on, the elder Croft plays a key role in the events of the film, working alongside his daughter and reluctantly leading Matthias to the tomb of Himiko. From a cinematic standpoint, it works better to have Lara and her father together than to just have her exploring by herself, and the final act of the film is definitely improved by having the two Crofts serve as each other's motivation, adding emotional stakes and dramatic tension to the already-exciting infiltration of Himiko's tomb.
