Do tu think Silas would fecha Katherine in season 5 ?

That would be nice :D

it could but i don't know

Uh no. Cant really tell. Anything can happen.

I think that she will not fecha Silas but she'll flirt with him ;)

Maybe, is Silas will pretend to be Stefan yes

Wait what?
I hope writers won't get this idea. I was already sick when they made her fall for Elijah - she clearly had feelings for Stefan after 150 years, during their 3x09 car ride (that was like 6 months hace in "TVD timetable"), and then suddenly she "loved" Elijah. If in S5 she'll be told to have "feelings" for Stefan again, or, even worse, Silas, I will totale lose hope that writers are still capable of creating a consistant character.
