The Starberries, my two cents.
Unlike what you might think, Power of his condition or what not, or him being fearless, I got to think about after seeing this, I think he was in some kind of chock, giving him adrenaline so the strawberries doesn’t affect him, he soon wakes up from this chock and again is allergic to this exotic fruit.
The Power of Chock, I would think.
