What If Tamlin Was Gravely Injured in ACOMAF?

I’ve been thinking a lot about the scene where Tamlin locks Feyre in the manor before leaving on a mission. He says it’s dangerous for her because of the creatures Amarantha unleashed on the Spring Court. Now imagine if, during that mission, Tamlin is gravely injured and bedridden. Lucian returns to the manor, only to find that Feyre has left. This leaves Lucien to figure out where she went and (maybe?) write a letter to the Hewn City, asking to speak with Feyre (assuming Rhysand is keeping her captive).

How do you think Feyre would react to that? Do you think Rhys would tell her or try to hide it? And if Feyre found out, do you think she would return, or would it change her perception of Tamlin locking her in the house? How do you think this would shift the dynamic between them?
