Well there are no signs that the lovely Gina is going anywhere tomorrow. I haven't studied the finer detail of when she came, and the visa situation but I'm basing it on several things
No sign of packing, although she might just do that tomorrow
No going away party, or even a few drinks, which, judging by what a fun girl she is, is pretty odd
If it was her last night, you would think that whoever she has met would be taking her out, or at least spending some time with her....
