On one hand, I think it would be funny.

On the other hand I don't know if Thad would get out of it

Thad: The only way I can get out from under this thing is to let someone kiss me? Well...I guess this is how I die

I mean, I’m sure someone will free him

XD That's what he's afraid of. He's still in a place where he's not too fond of touching

Yeah, that's why I'm hesitating on posting Nico

Sure Will could let him out, but anyone else and Nico would just be grumpy.

Yeah

I'm okay with the possible negative cr with him being grumpy at anyone who tries to help him. But i don't know how fun that would be for anyone else

It would be an interesting way to let one of Bart’s friends talk to him

oh God! yeah, that sure would be a hell of an introduction!

Tim: oh look, Thad is trapped by mistletoe and can't escape. This is a perfect time to do The Most(TM)

Thad: -Acting like a feral animal who would rather chew his own leg off then let someone touch their mouth to his cheek for five seconds-

June_bug: oh god! yeah that would possibly be a good opportunity for that

And then Cass pops in to peck Thad on the cheek and free him from the lectures.

Oh no! That's cute!

Also, "lectures". XD
yes, I'm sure that's all Tim has in mind. No threats at all
