I can imagine them finding out by these scenarios:

[hider=Scenario 1]

*The group is fighting monsters*

*Lia's arm is cut off*

*Lia calmly retreats, holding her dismembered arm to stitch back later*

*Group is dumbfounded*
[/hider]


[hider=Scenario 2]

*Lia's turn to cook with partner*

*While chopping something, she accidentally chops of her finger*

*She takes it and then begins stitching it back*

*Partner most likely freaks out*
