It appears that in the second part of the barbados episodes when she no longer has the bandage on there is evidence of a cut. She must of cut her arm (it doesn't appear to be too bad a cut) and it required a bandage for the filming of some of the scenes.
The proper biking arm signals to use while riding on the road are: Left turn: Extend your left arm straight out to the side. Right turn: Extend your right arm straight out to the side, or bend your left arm up at a right angle. Stop or slow down: Extend your left arm down at a right angle.
If your turn signals break, you can use hand signals to indicate your intentions while driving. To signal a left turn, extend your left arm straight out the window. To signal a right turn, extend your left arm out the window and bend it upward at a 90-degree angle.
