Whatever perfunctory resistance that inspires, Vergil ignores and presses a kiss to the crown of Nero's head before smoothing his hair back down with a fond smile. Yes, he is a stubborn brat. One that Vergil is immensely proud of and wouldn't likely be here without. Vergil doesn't say anything to it though, lowering his hand from Nero's hair to give him a few solid pats to his side.] And one that needs to not start winding himself up if he decides to stay here for the night unless he wants to be immensely cranky tomorrow because he stayed up too late.
