I saw this play out last time to the mafia's benefit.
I feel there's an added responsibility playing with a team, added pressure to keep active than there would be as just a townie. Lego Man may have real world commitments (obviously) but based on some of his longer posts he's been keeping up and actively looking for host...or we're lead to believe.
If he was having someone ghost write his posts, it may explain why XXX slipped through the cracks as they collaborated in the host thread.
Regardless of the switch, I've made my suspicion for Lego Man known before.
