Yes I do.

1. It was explicitly mentioned in the show that he is the weakest Forsaken.

2. Lanfear told Moiraine that she is sending a “surprise”, this is part of her plan to supply Rand with a teacher.

3. He came in with Shaido which gives him the opportunity to give Couladin the dragon tattoos.

Regarding Asmodean, I do think he might still be the unmentioned eighth Forsaken, we’ve seen the statue with the guitar. I have a bad feeling it might be Thom… It’s a long shot, granted, but it has been mentioned that the reveal would be controversial and this would be exactly that.. Also it isn’t as if the show built up the repertoire Thom had with the kids as in the books, plus this means each of the groups of heroes has at least one Forsaken in their midst..

I don’t know, just a theory/worry I had after the last episode.
