Angus Grimaldi

"That's nothing, mate. I grew up in Glasgow."- Grim, when held at knifepoint

Angus "Grim" Grimaldi is a character in Tomb Raider and is the helmsman of the Endurance before its destruction.

Background
Grim grew up in Gorbals, a notorious neighborhood of Glasgow, Scotland, which is itself considered the murder capital of the United Kingdom. As a child he always felt a kinship with water and often built makeshift boats out of junk and taught himself to sail on the river Clyde which flows through Glasgow. There is nothing about sailing and water that Grim does not know, and he has sailed all the oceans of the world, which included stints working for the Merchant Navy where he met Roth.

Roth and Grim found a kinship and stuck together after their service. They traveled the world and took any job that paid well, all of them dangerous and most of them legal. Grim and Roth saved each other’s skin on numerous occasions. When Roth purchased the Endurance, Roth would not trust anyone else but Grim at her helm.

It is also shown in his document that he use to know Lara's father, giving him a nickname "Dicky Croft" showing that they were close. They use to go on adventures together and says if he was there he would be studying "these bastards". This may be the reason why he is protective of Lara, giving up his life for her.
