After recovering from his injury, Mousinho re-joined Stevenage, on loan for the remainder of the season on 31 January 2014. The move meant that Mousinho had been signed by manager Graham Westley for a third time. He made his second debut for the club against Gillingham, the club he had been on loan at earlier in the season, as Stevenage won the match 3–1 at Broadhall Way. He scored once during the loan spell, in a 3–1 win over Tranmere Rovers on 8 March 2014. Mousinho made 16 appearances during the four-month agreement as Stevenage were relegated back to League Two. Mousinho was one of six players released by Preston on 20 May 2014.
