"A conspirator may give or take a card or item tile from another conspirator in the same space.
Note that card and item limits must not be violated at any time during this action. Items may be discarded at any time to make space for new ones"
but...cards? May them be discarded now, to make space for sharing a new one?
If your hand is full, you can still take more cards but you must then discard back to your maximum hand size before taking any other action.
