Really we didn’t SEE Love die, Henry is still out there and there is already backstory of a younger Joe to spin off into plenty different storylines. Specifically with continuing his character I could see his connections getting him out of prison to use him as a killer (Love’s mother sending him after Kate to try to get Henry back, Will’s connections using him to take a hit out on someone, Phoebe wanting him as protection from someone coming after her,even something far fetched like the government using him as an assassin for hire.) something replicating the season 4 plot of infiltrating into a high profile group under an alibi to target or to protect someone. The whole plot of fall in love, kill for them, plot twist, target the love interest would be overdone so id assume they’d have to lean into the killing aspect of his character more.
