That may be his Awakening . and if he were to fight Akainu , he'll awaken towards the end of the fight
personally i don't like if he gets Awakening by the time of final war though , because Ace himself who had years with Mera Mera didn't seem to have it ( otherwise he'd have blown other Commanders out of the water )
Luffy and Teach also doesn't have Awakenings yet despite been years with their DFs , for other examples
but i guess he could get it for plot reason
Edit - same for Shiryuu , btw .
