Robin could not look away from Marian as she explained; so, it was still uncertain? He jumped a little when the timer dinged, and then smiled as he took Marian's hand and got to his feet. Personally, he wanted to hurry in and see what the result was, but she seemed more hesitant, so he let her take the lead. Before walking in to the bathroom, he stopped her and pulled her gently into his arms.
"If it hasn't happened yet, we just keep trying. And, if it has..." He wanted to say, it will be the best thing ever, but she seemed so uncertain that he did not know if that would be a welcome statement. So, instead, he merely kissed the top of her head and held her another moment before stepping back.
