Passage: His involvement with Birmingham's first team increased, and on 27 January 2018, he was given a squad number and included among the substitutes for the FA Cup fourth-round visit to Premier League club Huddersfield Town. He remained unused as Birmingham drew the match, but made his senior debut in the replay ten days later. Use of a fourth substitute during extra time of an FA Cup tie, trialled in the later rounds of the 201617 edition, was permitted from the first round in 201718. Lakin became the first Birmingham player to be used under that arrangement when he replaced Jason Lowe after 101 minutes with his team already 31 down; the match finished as a 41 defeat. According to the Birmingham Mail, on his first involvement in the match, "he gathered possession on the edge of his own area, surged through his half and threaded a superb pass to Jota which set Blues away on the counter", showing the "sort of technical ability which has made him such a big hit in his first full season at Under 23 level." Two weeks later, Lakin signed a new contract to run until 2020, with a further one-year option in the club's favour.

Passage: Forman and Bishop William Elphinstone of Aberdeen were the principal envoys who brokered a seven-year truce with King Henry VII of England at Aytoun in September 1497. They were assisted by the Spanish ambassador Pedro de Ayala, who recommended in May 1498 that diplomatic correspondence to Scotland should be copied to Forman, his influential friend. The search for a queen for James began in 1499 when negotiators were appointed to treat with King Henry for the marriage of his eldest daughter, Princess Margaret. Dispensation from the pope for the marriage was received as both James and Margaret were cousins, descended from John Beaufort, Marquess of Dorset. On 8 October 1501, Forman, now postulate to the see of Moray, was commissioned along with Robert Blackadder, Archbishop of Glasgow and Patrick Hepburn, 1st Earl of Bothwell to conclude the treaty of marriage. In that same year, King Henry, in gratitude for his services required that Thomas Savage, Archbishop of York institute Forman as Rector of the parish church of Cottingham. On 26 November 1501, Pope Alexander VI provided Forman to the bishopric of Moray and then only a few months later in 1502, Bishop Forman concluded the Treaty of Perpetual Peace with England at Richmond Palace. The formal proceedings that finally concluded the marriage terms of King James and Margaret Tudor were conducted in Glasgow Cathedral on 10 December 1502 where Forman was a signatory. He was then appointed as a commissioner to oversee the exchange of the ratified marriage treaties at the courts of Henry and James. James designated Forman to conduct Margaret to Scotland but while in England, gave King Henry an undertaking that the King of Scots would not renew the league with France unless Henry was first consulted. The procession to Scotland took them to Fast Castle near Berwick where they stayed with Forman's sister Isabel and her husband Alexander Oliphant of Kellie. In 1509, Forman became commendator of Dryburgh Abbey and tried unsuccessfully to obtain the commendatorship of the wealthy abbey of Kelso in 1511. The lands and possessions of the parson of Boleskin, south of Inverness were given to Forman (as bishop of Moray) in 1511 and then in 1512 he became the Keeper of the castle of Darnaway, near Forres, Chamberlain of Moray and Custumar north of the River Spey.
