what was the love triangle ????
Clara who confesses she fell in love with the Doctor in the TNOTD prequel —> The Doctor (“smitten” with Clara, married to River) <— River
The unusual part was that River is in the Library and not alive before or after it as everyone thought before the finale.
And as Moffat said, it’s resolved. The Doctor showed he’s in love with River.
Clara is his buddy, not his love interest.
