User blog comment:TDWT: Planes, Trains, and Hot Air Mobiles/Duncey vs. Gwuncan/@comment-24971793-20140702124055/@comment-24971793-20140702184600

They where pretty flirtatious in TDI (in the brief interactions they had), episodes like "the big sleep" and "Hook, Line and screamer" illustrated how similar they where. Then two important plotlines of TDA where Trent going crazy over thinking that Gwen would cheat on him with Duncan. And Courtney accusing Duncan of cheating on her with Gwen. Finally in TDWT they get together, that's more build up than several of the other TD relationships. In retrospect, the lovetriangle was predictable ever since TDI. A triangle between a boy and a girl that has an opposite character and a girl that has the same character.

PS: Gwen didn't just act against people when she got provoked. She insulted every contestant (besides 5 or so) in the finale. She had a hatred for Geoff simply because he was the happy party guy type, she publicely insulted Lindsay before Lindsay ever did anything wrong. What in Island illustrated that she had a strong sense of loyalty?
