Connolly’s quantum leap to upset Ireland’s time travel plans?

Students of time travel will know this is precarious. In John Delaney’s grandiose vision, Ireland’s future has been mapped out and somehow it’s looking bright. Meanwhile, Mick McCarthy was summoned from the past to look after the present.
Now, in a dangerous quantum leap, Aaron Connolly is a saviour sent back from the future. Which puts us into tricky ‘grandfather paradox’ territory. Is he likely to change anything while he’s here that will prevent the future taking its natural course?
