I think Tommy has to die to give Catherine peace
If he locked up - unless brain damaged and not capable of anything
Then always a risk /chance ryan May went to see him when he's 18
Or he can cause trouble
So cleudo talk
pissing darious
With susan's wrench
At Neil's /Ann's house
If anyone else kills him then he would hang over their heads and won't be able to move on
Unless
Catherine while protecting Ryan
Tasers him and falls to death
Not sure where. A hill
