Romances:
If you wish to initiate a romance with a companion,
follow these simple guidelines: Flirt with the object of your affections
whenever possible. However, note that the presence of a Flirt option
isn’t always a true indication that a romance is possible.In Act 2, try
to ensure that your visits to Hawke’s abode occur at night. If your
desired squeeze is present on arrival, use the Flirt option to initiate
the next stage. When the option arises in conversation, enquire about
living together.After the romance begins, do notmake come-hither eyes
at other companions or NPCs: this will not end well. Nor, for that
matter, will any degree of ambivalence or outright rejection.For the
rest of the story, develop the relationship gauge to maximum friendship
or rivalry, complete all companion quests (including any ambient
situational conversations that may occur), deliver the necessary gifts,
then share a moment with Hawke’s loved one in the calm before the storm
during Dragon Age II’s epic conclusion (you’ll know it when you get
there).For Isabela and
Sebastian(
),
the above technique only partially applies. The Companion
Analysis section at the conclusion of this chapter contains a
complete guide to wooing both (though Sebastian only ever offers a
chaste relationship) but is surrounded by heavy spoilers if you are still on your first playthrough
So I think Sebastian is a proper romance but there isn't a sex scene
