@ LatZee - I don't know if there is a deed - or even a leather jacket - I am just going by Angel's speech. I can't get beyond that to see what he gives me.

Maria, automatically joins the squad after having met Angel.
Like Skryider, there's some time between the end of the quest and her joining the squad.
After having talked to Angel, Maria will leave the leather shop and, once standing on the road, join the player's squad.
In that time between the end of the quest (history log beeps) and her joining, the player can go to the strategic screen if he doesn't want Maria to join the squad.
