It's not as if Dean doesn't want to help Seamus. He wants to, so badly it's hurting him physically, emotionally and academically. He can't concentrate anymore; he can only think of Seamus and what is he going to be like when I get home? Is he going to be there at all, or will he be gone to Lavender's again? Or somewhere else? Is he going to be okay? Am I going to be okay? No, that doesn't matter, Seamus is more important.
But Dean has always been better with a quill than with words and he's always expressed himself with a paintbrush rather than speech. He's not cut out for this. He's trying, but what can he do other than brew Seamus a cuppa and tell him it's going to be alright? It's not. They both know it. Maybe Dean would be better off bringing Shay to St Mungo's; surely they have Healers there who will know what to do. How will he bring it up without offending Seamus, though? He is a grown man, and a Gryffindor at that. He still has his pride, hopefully. Is it too late? This has been happening for nearly two years, and it's only getting worse as time wears on.
No. It can't be too late. He has to save Seamus from himself, and if that means getting help elsewhere, then so be it.
Dean resolves to tell Shay of his plan tonight at supper.
