The cunning Slytherin Tom Felton was prepared for this though, including the hashtag #gryffindork after Matt Lewis’ refusal.
It appears that Tom Felton made a valiant effort, even tempting Matthew Lewis with some sweet Slytherin swag in the form of a nice green backpack sporting the green and silver house crest.
Yet despite Tom Felton’s claim on Instagram that his co-star was close to converting, Matthew Lewis looks deeply unmoved by this gesture, remaining as stout a Gryffindor as ever.
Despite the neverending battle for house supremacy, for fans of the Harry Potter series, it is just cool to see these two actors reunited and having fun together in real life.
