Seth came out of the room he was in when he heard voices coming from downstairs and looked to see Mason "Welcome back." He spoke to him simply as nothing else needed to be said as he listened to everyone else greet Mason but was particularly interested in Mina's choice of words for her response "Shouldn't that be good to see you back brother or something similar like that?" Seth asked out loud so everyone else could hear and force a response out of Mina as he started to grow suspicious of her, the more he thought about it Mina did not look too much like Mason either.
