It does have a weird tone. I went with the drow with Gale once for science because yt only had videos about Astarion then - and I ended up feeling proud of Gale and how he took himself out of the situation eventually and extremely ashamed of my own character. I doubt this is the intention.
Gale's reaction/ feelings on the matter make me wonder what a nervous wreck he must be, if you chose the bed in act2. ^^;
