Dear all,
I have encountered people with this particular problem before but I find that the solution offered to them was not of any use to me.
To explain myself better, I am trying to get into the castle with Serana. The problem is that as soon as we land on this island and I start to walk slowly up the bridge so she can follow me, I do not get any interaction with her. She remains as silent as the night and upon arriving to the gate, that lovely old man keeps telling me to bugger off. I have tried loading different autosaves and travelling from castle to other places and vica versa. In the end nothing works. Now my last normal save is about 8 levels earlier ( yes I blame my lazyness) and I therefore hope that there is some sort of glitch or whatever that could be used.
Since its on ps3 I cannot use any console commands (lame) and the only other solution I've come to read is of running into a plate that I need to hold against the wall. Even though irl im a big fan of running into walls with plates on them, I came to the sad conclusion that it did not work for me on the ps3.
I hope that one of you bright fellow skyrim lovers knows of any solution (well I'd rather avoid the answers of load ur older save).
Lots of hugs and kisses!
