Partner has no reason to double. The other side made a free bid at the three level in hearts and his partner 'after' making a takeout double 'jumped' to 4S.
Partner has AKxxxx of a suit that you supported so he can maybe hope for one trick in diamonds. That jump to 4S showed a 'big' hand so doubling is borderline crazy.
If partner passes, you can look at your hand and decide if you like your hand for defense. Somehow I doubt that anyone would double with this 4HCP collection of Queen/Jacks in a red two suiter.
Why didn't I bid 1H earlier? The hand has much better potential if partner 'fits' hearts.

Robert
