i think hes bipolar

' Jacob turned into boyfriend mode then, smiling down at Renesmé with a goofy grin. Me and Seth had a hunch that he was bipolar.'

From a my fanfiction 'blue eyed devil'.
There's jacob and Renesme together, aw, and then seth (small) and matt (tall).
At the bottom is from another bit when hes with emily. ya know, yadda yadda, cant have a mate cos i might hurt them.
biro and black pen, wonderful history lesson!
